(transition time does not include clock and data feedthrough). notes on mpu port 8 t 23 and t 24 are measured with the load circuit of figure 1 and defined as the time required for an output to cross 0.4 v or 2.4 v. 9 t 25 and t 26 are derived from the measured time taken by the data outputs to change by 0.5 v when loaded with the circuit of figure 1. the measured numbers are then extrapolated back to remove the effects of charging the 100 pf capacitor. this means that the times t 25 and t 26 , quoted in the timing characteristics are the true values for the device and as such are independent of external loading capacitances. specifications subject to change without notice. 100pf to output pin i source i sink +2.1v figure 1. load circuit for databus access and relinquish times

(this mode is not available for the adv7162.) palette select mode is used to multiplex the rgb outputs of a number of devices. when the palette mode inputs match the ps bits in the mode register, the part operates as normal. when there is a mismatch, the rgb outputs are switched to zero, allowing the rgb outputs of another device to drive the monitor. loadin pixel data load input (ttl compatible input): this input latches the multiplexed pixel data, in- cluding ps0-ps1, blank , trisync , sync and odd/ even into the device. loadout pixel data load output (ttl compatible output): this output control signal runs at a divided down frequency of the pixel clock. its frequency is a function of the multiplex rate. it can be used to directly or indirectly drive loadin. f loadout = f clock /m where (m = 2 for 2:1 multiplex mode) (m = 4 for 4:1 multiplex mode) (m = 8 for 8:1 multiplex mode) prgckout programmable clock output (ttl compatible output): this output control signal runs at a divided down frequency of the pixel clock. its frequency is user programmable and is determined by bits cr30 and cr31 of command register 3. f prgckout = f clock /n where n = 4, 8, 16 & 32 sckin video shift clock input (ttl compatible input): the signal on this input is internally gated syn- chronously with the blank signal. the resultant output, sckout, is a video clocking signal that is stopped during video blanking periods. it is normally driven by a divided down version of the clock frequency. sckout video shift clock output (ttl compatible output): this output is a synchronously gated version of sckin and blank . sckout is a video clocking signal that is stopped during video blanking periods. clock, clock clock inputs (ecl compatible inputs): these differential clock inputs are designed to be driven by ecl logic levels configured for single supply (+5 v) operation. the clock rate is normally the pixel clock rate of the system. pll ref pll clock input (ttl compatible input): this clock input is designed to be driven by ttl logic levels. the pll is then configured to output a specific frequency depending on the pll registers. see pll section for more detail. blank composite blank (ttl compatible input): this video control signal drives the analog outputs to the blanking level. sync composite-sync input (ttl compatible input): this video control signal drives any of the analog outputs to the sync level. it is only asserted during the blanking period. cr22 in command register 2 must be set if sync is to be decoded onto the iog analog output, cr41 in command register 4 must be set if sync is to be decoded onto the ior analog output, cr42 in command register 4 must be set if sync is to be decoded onto the iob analog output, otherwise the sync input is ignored.

ADV7160/adv7162 rev. 0 C15C (continued from page 1) the ADV7160/adv7162 integrates a number of graphic func- tions onto one device allowing 24-bit direct true-color (30-bit corrected-color) operation at the maximum screen resolution of 1600 1280 at a refresh rate of 85 hz. the ADV7160/ adv7162 integrates a 256 30 color palette ram with three high speed, 10-bit, digital-to analog converters (rgb dacs). it also contains a user-definable, x-windows compatible, 64 64 2 cursor generator and associated ram. an on-board overlay palette ram is also included. the devices 96-bit pro- grammable pixel port enables various data formats to be input to the part. an on-board clock and synchronization circuit controls all clocking functions for both the part and graphics subsystem. there are two video data paths through the adv716 0/adv7162. one routes the data from the pixel port through the ram to the dacs, the other bypasses the ram and routes data direct from the pixel port to the dacs. either path can be selected on a pixel by pixel basis. this allows for the overlay of an active video window on a graphics background. the on-board palette priority select inputs enable multiple pal- ette devices to be connected together for use in multipalette and window applications. the part is controlled and programmed through the microprocessor (mpu) port. one ttl input signal pll ref are required to get the part operational. no additional signals or external glue logic are re- quired to get the pixel port and clock control circuit of the part operational. multiplexer 24 24 24 24 24 8 8 8 red green blue a b c d figure 15. multiplexed color inputs for the ADV7160/adv7162 pixel port (color data) the ADV7160/adv7162 has 96 color data inputs. the part has four (for 4:1 multiplexing) 24-bit wide direct color data in- puts. these are user programmed to support a number of color data formats including 24-bit true-color, 16-bit true-color, 15-bit true-color in 4:1 and 2:1 multiplex modes, and 8-bit pseudo-color (see multiplexing section) in 8:1, 4:1 and 2:1 multiplex modes. color data is latched into the parts pixel port on every rising edge of loadin (see timing waveform, figure 4). the required frequency of loadin is determined by the multiplex rate, where f loadin = f clock /8 8:1 multiplex mode f loadin = f clock /4 4:1 multiplex mode f loadin = f clock /2 2:1 multiplex mode circuit details and operation overview digital video or pixel data is latched into the ADV7160/adv7162 over the devices pixel port. this data acts as a pointer to on- board color palette ram. the data at the ram address pointed to is latched to the digital-to-analog converters (dacs) and out- put as an rgb analog video signal. for the purposes of clarity of description, the ADV7160/adv7162 is broken down into three separate functional blocks. these are: 1. pixel port and clock control circuit 2. mpu port, registers and color palette 3. digital-to-analog converters and video outputs pixel port & clock control circuit the pixel port of the ADV7160/adv7162 is directly interfaced to the video/graphics pipeline of a computer graphics subsystem. it is connected directly or through a gate array to the video ram of the systems frame-buffer (video memory). the pixel port on the device consists of: color data red, green, blue pixel controls sync , blank , trisync palette selects ps0 a-d , ps1 a-d the associated clocking signals for the pixel port include: clock inputs clock, clock , pll ref , loadin, sckin clock outputs loadout, prgckout, sckout these on-board clock control signals are included to simplify in- terfacing between the part and the frame buffer. either two control input signals clock and clock (ecl levels) or the 30 bits of resolution, associated with the color look-up table and triple 10-bit dac, realizes 24-bit true-color resolution, while also allowing for the on-board implementation of linear- ization algorithms, such as gamma-correction and monitor callibration. this allows effective 30-bit true-color operation. the on-chip video clock controller circuit generates all the inter- nal clocking and some additional external clocking signals. the high accuracy, low jitter on board pll eliminates the need for an external high speed clock generator. the pll can be pro- grammed to produce a pixel clock that is a multiple of the pll reference clock. the adv7162 is packaged in a standard plastic 160-pin quad flatpack (qfp). the ADV7160 is packaged in a plastic 160-pin power quad flatpack (pquad). superior thermal distribution is achieved by the inclusion of a copper heatslug, within the standard package outline, to which the die is attached. this part is ideally suited for high performance applications where external environmental conditions are unpredictable and uncontrollable.
rev. 0 C16C ADV7160/adv7162 other pixel data signals latched into the device by loadin include sync , blank , trisync and ps0 a-d C ps1 a-d . internally, data is pipelined through the part by the differential pixel clock inputs, clock and clock or by the internal pixel clock generated by the pll on-board. the loadin control signal need only have a frequency synchronous relation- ship to the pixel clock (see pipeline delay & on-board calibration section). a completely phase independent loadin signal can be used with the ADV7160/adv7162, allowing the clock to occur anywhere during the loadin cycle. alternatively, the loadout signal of the ADV7160/adv7162 can be used. loadout can be connected either directly or indirectly to loadin. its frequency is automatically set to the correct loadin requirement. sync , blank the blank and sync video control signals drive the analog outputs to the blank and sync levels respectively. these signals are latched into the part on the rising edge of loadin. the sync information is encoded onto the iog analog signal when bit cr22 of command register 2 is set to 1, the ior analog signal when bit cr41 of command register 4 is set to 1 and the iob analog signal when bit cr42 of command register 4 is set to 1. the sync input is ignored if cr22, cr41 and cr42 are set to logic 0. syncout in some applications where it is not permissible to encode sync on green (iog), blue (iob), or red (ior), syncout can be used as a separate ttl digital sync output. this has the advantage over an independent (of the ADV7160/adv 7162) sync in that it does not necessitate knowing the absolute pipe- line delay of the part. this allows complete independence between loadin/pixel data and clock. the sync input is connected to the device as normal with bit cr22 of com- mand register 2, bit cr41 of command register 4 and bit cr42 of command register 4 are set to 0 thereby preventing sync from being encoded onto iog, ior and iob. the out- put signal generates a ttl syncout with correct pipeline delay which is capable of directly driving the composite sync signal of a computer monitor. trisync this input is used to generate a hdtv sync on any of the dac outputs. bit cr17 of command register 1 is set to 1, en- abling trisync . when trisync is low, the analog output which has sync enabled goes to the tri-sync level. ps0 a-d Cps1 a-d (palette priority select inputs) these multifunctional ttl compatible inputs can be config- ured for three separate functions. the eight ps inputs are mul- tiplexed to provide two bits which are used to provide one of three different functions. the function is selected by bit cr14 and bit cr15 of command register 1. cr15 cr14 color mode 0 0 palette select mode 0 1 bypass mode control (ADV7160 only) 1 0 overlay color mode 1 1 ignore ps inputs however, in 8:1 mode, for 8-bit pseudo color, the unused blue pixel inputs are used to provide 8 extra ps inputs. the bypass mode is unavailable in this case. palette select mode these pixel port select inputs effectively determine whether the devices rgb analog outputs are turned-on or shut down. when the analog outputs are shut down, ior, iog and iob are forced to 0 ma regardless of the state of the pixel and control data inputs. this state is determined on a pixel by pixel basis as the ps0Cps1 inputs are multiplexed in exactly the same format as the pixel port color data. these controls allow for switching between multiple palette devices. if the values of ps0 and ps1 match the values programmed into bits mr16 and mr17 of the mode register, then the device is selected, if there is no match the device is effectively shut down. bypass mode control (ADV7160 only) in this mode ps1 is used to switch between one of the color modes through the color palette and one of the palette bypass modes on a pixel by pixel basis. the color mode through the palette is selected using bits cr27Ccr24 of command regis- ter 2. the bypass color mode is selected using bits cr17 and cr16 of command register 1. ps1 then switches between the palette color mode, and the bypass color mode. the ps0 in- put continues to act as an overlay input, allowing overlay color 1 to be displayed. ps0 ps1 color mode 0 0 palette color mode (cr27Ccr24) 0 1 bypass color mode (cr17Ccr16) 1 x overlay color 1 this mode is not available if using the adv7162. overlay color mode in this mode, the ps inputs provide control for a three color overlay. whenever the value other than 00 is placed on the overlay inputs, the corresponding overlay color is displayed. when the overlay inputs contain 00 the color is specified by the main pixel inputs. clock control circuit the ADV7160/adv7162 has an integrated clock control cir- cuit (figure 16). this circuit is capable of both generating the ADV7160/adv7162s internal clocking signals as well as exter- nal graphics subsystem clocking signals. total system synchro- nization can be attained by using the parts output clocking signals to drive the controlling graphics processors master clock as well as the video frame buffers shift clock signals. clock, clock inputs the clock control circuit is driven by the pixel clock inputs, clock and clock . these inputs can be driven by a differ- ential ecl oscillator running from a +5 v supply.

rev. 0 C18C ADV7160/adv7162 the sckout signal is essentially the video memory shift con- trol signal. it is stopped during the screen retrace. figure 19 shows a suggested frame buffer to ADV7160/adv7162 interface. this is a minimum chip solution and allows the ADV7160/adv7162 con- trol the overall graphics system clocking and synchronization. loadout sckout ADV7160/ adv7162 pixel data loadin sckin blank video frame buffer figure 19. ADV7160/adv7162 interface using sckin and sckout pll the on-board pll can be used as an alternative clock source. this eliminates the need for an external high speed clock gen- erator such as a crystal oscillator. with the pll, it is possible to generate an internal clock whose frequency is a multiple of the pll reference frequency (pll ref ). internal pll operation is selected by setting cr56 of command register 5 to logic 1. the pll registers can be programmed to set up the frequency required. the block diagram of the phase locked loop is shown in fig- ure 20. the blocks consist of a phase frequency detector, a charge pump, a loop filter, a voltage controlled oscillator and a programmable divider. voltage controlled oscillator charge pump phase detector reference divider pll ref f pd feedback divider f vco o/p divider f out f pd figure 20. pll block diagram the phase frequency detector drives the voltage controlled oscil- lator (vco), to a frequency that will cause the two inputs to the phase frequency detector to be matched in frequency and phase. the corresponding output of the vco can be calculated as: vco = pll ref feedback divider reference divider the reference divider is set by a combination of the contents of the pll r register and the rsel bit. the pll r register has a resolution of 7 bits. it is programmed by setting the pll r register located at control register address 00ch . the pll r register can be set from 01h to 7fh. it should not be set to 00h. if this register contains 00h, then the pll stops. there- fore, the reference divider can be set from 3 to 129 in steps of one, or from 130 to 258 in steps of two by setting the rsel bit. the rsel bit is accessed by changing bit pcr1 of the pll control register. the feedback divider is set by a combina- tion of the contents of the pll v register, the vsel bit and the s value. the s value is set up in pcr7 and pcr6 of the pll command register. this s value allows a better resolu- tion when setting the feedback divider value. the pll v reg- ister has a resolution of 7 bits. it is programmed by setting the pll v register located at control register address 00fh .the pll v register can be set from 01h to 7fh. it should not be set to 00h. if this register contains 00h, then the pll stops. therefore the feedback divider can be set from 12 to 519 in steps of one, or from 520 to 1038 in steps of two by setting the vsel bit. the vsel bit is accessed by changing bit pcr2 of the pll control register. the p counter divides the output from the oscillator by 1, 2, 4 or 8 as determined by psel1 and psel0 which are set in bits pcr5 and pcr4 of the pll con- trol register. this post-scaler is useful in the generation of lower frequencies as the vco has been optimized for high frequency operation.

(note: data on unused pixel inputs is ignored.) there are three modes of operation for 8-bit pseudo color. each mode maps the input pixel data differently. data can be input into one of the three color channels, r7Cr0 or g7Cg0 or b7Cb0. in 24-bit palette bypass mode, the red, blue and green color channels bypass the pixel mask and the color palette. each 8- bit color channel is mapped onto the 8 msbs of the correspond- ing 10-bit dac input. the two lsbs on each dac are zeros. the bypass mode can be selected in two ways, by using cr27C cr24 of command register 2 or on a pixel by pixel basis using the ps inputs (ADV7160 only). in 16-bit palette bypass mode, the color channels bypass the pixel mask and the color palette. the 8-bits of red pixel data and 8-bits of green pixel data are mapped onto the 5 msbs of the red and blue dac input and the 6 msbs of the green dac input as shown in figure 29. the remaining lsbs on each dac are zeros. the bypass mode can be selected in two ways, by using cr27Ccr24 of command register 2 or on a pixel by pixel basis using the ps inputs (ADV7160 only).

rev. 0 C26C ADV7160/adv7162 register programming the following section describes each register, including address register, mode register and each of the control registers in terms of its configuration. address register (a10Ca0) as illustrated in the previous tables, the c1 and c0 control in- puts, in conjunction with this address register specify which control register, or color palette location is accessed by the mpu port. the address register is 11 bits wide and can be read from as well as written to. to access the address register, two consecutive mpu accesses with c1 and c0 set to logic 0 are required. the first one accesses the low byte; and when a second access of the same type is performed, i.e., two consecu- tive reads or two consecutive writes, the high byte is accessed. if the type of access is changed, or if an access to a different reg- ister is inserted between the first and the second, then the sec- ond access will access the low byte again. when writing to or reading from the color palette on a sequential basis, only the start address needs to be written. after a red, green and blue write sequence, the address register is automatically incremented. mode register (mr1) the mode register is a 10-bit wide register. however for pro- gramming purposes, it may be considered as an 8-bit wide regis- ter (mr19 and mr18 are both reserved). it is denoted as mr17Cmr10 for simplification purposes. figure 39 shows the various operations under the control of the mode register. this register can be read from as well written to. in read mode, if mr19 and mr18 are read back, they are both returned as zeros. mode register bit description reset control (mr10) this bit is used to reset the pixel port sampling sequence. this ensures that the pixel sequence abcd starts at a. it is reset by writing a 1 followed by a 0 followed by a 1. this bit must run this cycle during the initialization sequence. ram-dac resolution control (mr11) when this is programmed with a 1, the ram is 30 bits deep (10 bits each for red, green and blue), and each of the three dacs is configured for 10-bit resolution. when mr11 is pro- grammed with a 0, the ram is 24 bits deep (8 bits each for red, green and blue), and the dacs are configured for 8-bit resolution. the two lsbs of the 10-bit dacs are pulled down to zero in 8-bit ram-dac mode. mpu data bus width (mr12) this bit determines the width of the mpu port. it is configured as either a 10-bit wide (d9Cd0) or 8-bit wide (d7Cd0) bus. ten-bit data can be written to the device when configured 8-bit wide mode. the 8 msbs are first written on d7Cd0, then the two lsbs are written over d1Cd0. bits d9Cd8 are zeros in 8- bit mode. operational mode control (mr14Cmr13) when mr14 and mr13 are 0 the part operates in normal mode. calibrate loadin (mr15) this bit automatically calibrates the on-board loadin/ loadout synchronization circuit. a 0 to 1 transition initiates calibration. this bit is set to 0 in normal operation. see pipeline delay & calibration section. this bit must run this cycle during the initialization sequence. palette select match bits control (mr17Cmr16) these bits allow multiple palette devices to work together. when bits ps1 and ps0 match mr17 and mr16 respectively, the device is selected. if these bits do not match, the device is not selected and the analog video outputs drive 0 ma. see palette priority select inputs section. control registers a large bank of registers plus the 64 64 cursor image can be accessed through the control register. access is made first by writing the address register with the appropriate address to point to the particular control register (see figure 34), and figure 39. mode register 1 (mr1) (mr19Cmr10) reserved* mr19 mr18 mr17 mr16 mr12 mr15 pcr4 mr13 mr11 mr10 * these bits are read-only reserved bits. a read cycle will return zeros "00." palette select match bits control mr16 ps0 mr17 ps1 mpu data bus width mr12 0 8-bit (d7?0) 1 10-bit (d9?0) operational mode control 0 0 0 1 1 0 1 1 mr14 mr13 normal operation reserved reserved reserved mr14 calibrate loadin mr15 ram-dac resolution control mr11 0 8-bit 1 10-bit reset control mr10
ADV7160/adv7162 rev. 0 C27C then performing an mpu access to the control register. when accessing control registers in the range 200h to 204h, and when accessing the cursor image, the address register auto- increments after each register access. on accessing the last cur- sor image location at address 7ffh, the address register reverts to address 000h. the address register also auto-increments after a blue access, when accessing color registers in the address range 303h to 304h. id register (address reg (a10Ca0) = 003h) this is an 8-bit wide identification read-only register. for the ADV7160 it will always return the hexadecimal value 76h. for the adv7162 it will always return the hexadecimal value 79h. pixel mask register (address reg (a10Ca0) = 004h) the contents of the pixel mask register are individually bit-wise logically anded with the red, green and blue pixel input stream of data. it is an 8-bit read/write register with d0 corre- sponding to r0, g0 and b0. for normal operation, this register is set with ffh. command register 1 (cr1) (address reg (a10Ca0) = 005h) this register contains a number of control bits as shown in the diagram. cr1 is a 10-bit wide register. however for program- ming purposes, it may be considered as an 8-bit wide register (cr19 to cr18 reserved). figure 40 shows the various operations under the control of cr1. this register can be read from as well written to. in write mode zero should be written to cr12. in read mode, cr19 and cr18 are returned as zeros. command register 1-bit description calibration control (cr10) this bit automatically calibrates the on-board loadin/ loadout synchronization circuit on every vertical sync. mr15 of mode register mr1 must be set to 0. figure 40. command register 1 (cr1) (cr19Ccr10) hi-byte control (cr13) this bit enables access to the hi byte of the address register. when cr13 is set to logic 0, the part is compatible to the adv7150. to access the hi-byte of the address register, this bit is set to logic 1. ps function control (cr15Ccr14) these bits control the functions of the ps inputs. they are used to enable the overlay mode, bypass mode or the palette select mode. in palette select mode (cr15 and cr14 = 0), these inputs are used to multiplex the rgb outputs of a number of devices. on a pixel by pixel basis, ps1 and ps0 are com- pared against the ps match bits, mr17 and mr16. if they match, then the part behaves normally. if they dont match, then the analog output currents are switched to zero for that clock cycle, thus allowing another device, whose ps match bits match during this time, to drive the monitor. in bypass mode (cr15 = 0, cr14 = 1), ps1 is used to switch between one of the color modes through the color palette and one of the pal- ette bypass modes, on a pixel by pixel basis. the color mode through the palette is selected using cr17 and cr16. it is il- legal to program cr27 to cr24 to select one of the bypass modes when using the ps bits to select a bypass mode at the pixel rate. this switching on a pixel by pixel basis is only allowed when using an ADV7160 device. therefore, for the adv7162, this mode (cr15 = 0, cr14 = 1), is reserved and should not be used. in overlay mode (cr15 = 1, cr14 = 0), the ps inputs provide control for a three color overlay. whenever a value other than 00 is placed on the overlay inputs, the correspond- ing overlay color is displayed. when the overlay inputs contain 00, the color is specified by the pixel inputs. when cr15 and cr14 = 1, the ps inputs are completely ignored. there is no overlay, no bypass switching and the rgb outputs are enabled. bypass color mode control (cr17Ccr16) these bits control the mode during bypass switching. there are three different modes: 24-bit bypass, 16-bit bypass or 15-bit bypass mode. reserved* cr19 cr18 cr17 cr16 cr12 cr15 cr14 cr13 cr11 cr10 * these bits are read-only reserved bits. a read cycle will return zeros "00." test mode control cr11 1 enable test mode 0 disable ps function control 0 0 0 1 1 0 1 1 cr15 cr14 palette selects bypass mode** overlays ignore ps inputs **this mode is only available on the ADV7160. it is reserved on the adv7162. address register hi-byte control cr13 0 no access to hi-byte (adv7150 compatible) cr12 (0) bypass color mode 0 0 0 1 1 0 1 1 cr17 cr16 15-bit bypass 16-bit bypass 24-bit bypass reserved this bit should be set to zero calibration control cr10 1 calibrates on every vertical sync (mr15=0) 0 disable 1 access to hi-byte

ADV7160/adv7162 rev. 0 C31C pll v register (address reg (a10Ca0) = 00fh) this register is a read only 10-bit register. however v9Cv8 are reserved bits, containing zeros. bit v7 is a read only bit. this bit should be masked in software on readback as its value may be indeterminate. therefore, the pll v register may be treated as a 7-bit wide register. this register, together with the vsel bit in the pll control register, controls the feedback divider of the on-board pll. 64 64 cursor the ADV7160/adv7162 has a 64 64 cursor generator on board. several of the control registers control the cursor. these will be described in detail. the cursor-x and cursor-y registers specify the position the cursor is to be placed on the screen. the origin (0, 0) of the cursor is top left. the position of the cursor is taken relative to this point, allowing the cursor- x and cursor-y registers to be programmed with negative num- bers and thus allow the cursor to be partially or completely off the screen. the cursor can work as an x-11 or xga cursor, controlled by bits ccr0 and ccr1 of the cursor control register. the screen x and y coordinates are measured from the rising edge of blank . the first pixel after the rising edge of blank corresponds to the origin (0, 0). the vertical retrace time is ex- tracted from the composite sync and blank inputs. the start of vertical retrace is recognized by counting a second ris- ing edge on sync while blank remains low. the next rising edge on blank is the start of line 0. cursor x-lo and cursor x-hi register (address reg (a10Ca0) = 200h and 201h) these 8-bit registers together form a 16-bit 2s complement rep- resentation of the cursor x-coordinate on the screen. the valid range for the cursor x-coordinate is fffh. the negative number representation allows for part or all of the cursor to be displayed off the left-hand edge of the screen cursor y-lo and cursor y-hi register (address reg (a10Ca0) = 202h and 203h) these 8-bit registers together form a 16-bit 2s complement rep- resentation of the cursor x-coordinate on the screen. the valid range for the cursor x-coordinate is fffh. the negative number representation allows for part or all of the cursor to be displayed off the top/left of the screen. when accessing the cursor x and y registers, the address regis- ter auto-increments after each access. there are no restrictions on updating the cursor coordinate registers other than they must all be written in the order x-low, x-hi, y-low, y-hi to update the coordinates. only one cursor is displayed per frame, at the last x and y coordinates written. access to these registers is independent of the databus being configured for 8- or 10-bit operation. cursor color 1 and cursor color 2 register (address reg (a10Ca0) = 304h and 303h) each of these color registers are 30 bits wide, made up of 10 bits for red, 10 bits for green and 10 bits for blue. access to these registers behaves in the same way as access to the color palette with respect to the different combinations of 10/8-bit databus and 10/8-bit dac resolution. cursor image (address reg (a10Ca0) = 400hC7ffh) this region contains the 64 64 2-bit cursor image. eight bits are stored at each address. with two bits per cursor pixel, four horizontally adjacent pixels are stored at each address. as each address location in the cursor image is filled, the progres- sion is from left to right until a line is filled and top to bottom until all the lines are filled. the cursor can be displayed on both an interlaced and noninterlaced system, as controlled by ccr3 of the cursor control register. on an interlaced system, only one cursor can be displayed per field. the odd/ even input indicates which field of the frame is being displayed. cursor y coordinate even the even field starts with line 0 of the cursor image on line y of the frame. subsequent even lines of the cursor image are dis- played on subsequent lines of the even field. on the even field, the frame line counter starts at 0 and increments by 2 at the end of every even field line. the odd field starts with line 1 of the cursor image on line y + 1 of the frame. subsequent odd lines of the cursor image are displayed on subsequent lines of the odd field. on the odd field, the frame line counter starts at 1 and increments by 2 at the end of every odd field line. cursor y coordinate odd the even field starts with line 1 of the cursor image on line y + 1 of the frame. subsequent even lines of the cursor image are displayed on subsequent lines of the even field. on the even field, the frame line counter starts at 1 and increments by 2 at the end of every even field line. the odd field starts with line 0 of the cursor image on line y of the frame. subsequent odd lines of the cursor image are displayed on subsequent lines of the odd field. on the odd field, the frame line counter starts at 0 and increments by 2 at the end of every odd field line. cursor control register (address reg (a10Ca0) = 204h) this register contains a number of control bits. ccr is a 10-bit wide register. however for programming purposes, it may be considered as an 8-bit wide register (ccr8 and ccr9 are both reserved). in write mode zero should be written to ccr4 to ccr7. in read mode, ccr8 and ccr9 are all returned as zeros. figure 45 shows the various operations under the control of ccr. cursor control register bit description cursor mode control (ccr1Cccr0) these bits specify which type of cursor is being used. each cur- sor pixel value controls

rev. 0 C34C ADV7160/adv7162 appendix 1 board design and layout considerations the ADV7160/adv7162 is a highly integrated circuit contain- ing both precision analog and high speed digital circuitry. it has been designed to minimize interference effects on the integrity of the analog circuitry by the high speed digital circuitry. it is imperative that these same design and layout techniques be ap- plied to the system level design such that high speed, accurate performance is achieved. the recommended analog circuit layout shows the analog interface between the device and monitor. the layout should be optimized for lowest noise on the ADV7160/adv7162 power and ground lines by shielding the digital inputs and providing good decoupling. the lead length between groups of v aa and gnd pins should by minimized so as to minimize inductive ringing. ground planes the ground plane should encompass all ADV7160/adv7162 ground pins, voltage reference circuitry, power supply bypass circuitry for the ADV7160/adv7162, the analog output traces, and all the digital signal traces leading up to the ADV7160/ adv7162. the ground plane is the graphics board's common ground plane. power planes the ADV7160/adv7162 and any associated analog circuitry should have its own power plane, referred to as the analog power plane (v aa ). this power plane should be connected to the regular pcb power plane (v cc ) at a single point through a ferrite bead. this bead should be located within three inches of the ADV7160/adv7162. the pcb power plane should provide power to all digital logic on the pc board, and the analog power plane should provide power to all ADV7160/adv7162 power pins and voltage refer- ence circuitry. plane-to-plane noise coupling can be reduced by ensuring that portions of the regular pcb power and ground planes do not overlay portions of the analog power plane, unless they can be arranged such that the plane-to-plane noise is common mode. supply decoupling for optimum performance, bypass capacitors should be in- stalled using the shortest leads possible, consistent with reliable operation, to reduce the lead inductance. best performance is obtained with 0.1 m f ceramic capacitor decoupling. each group of v aa pins on the ADV7160/adv7162 must have at least one 0.1 m f decoupling capacitor to gnd. these capacitors should be placed as close as possible to the device. it is important to note that while the ADV7160/adv7162 con- tains circuitry to reject power supply noise, this rejection de- creases with frequency. if a high frequency switching power supply is used, the designer should pay close attention to reduc- ing power supply noise and consider using a three terminal volt- age regulator for supplying power to the analog power plane. digital signal interconnect the digital inputs to the ADV7160/adv7162 should be iso- lated as much as possible from the analog outputs and other analog circuitry. also, these input signals should not overlay the analog power plane. due to the high clock rates involved, long clock lines to the ADV7160/adv7162 should be avoided to reduce noise pickup. any active termination resistors for the digital inputs should be connected to the regular pcb power plane (v cc ), and not the analog power plane. analog signal interconnect the ADV7160/adv7162 should be located as close as possible to the output connectors to minimize noise pickup and reflec- tions due to impedance mismatch. the video output signals should overlay the ground plane, and not the analog power plane, to maximize the high frequency power supply rejection. digital inputs, especially pixel data inputs and clocking signals (clock, loadout, loadin, etc.) should never overlay any of the analog signal circuitry and should be kept as far away as possible. for best performance, the analog outputs (ior, iog, iob) should each have a 75 w load resistor connected to gnd. these resistors should be placed as close as possible to the ADV7160/adv7162 so as to minimize reflections.

rev. 0 C42C ADV7160/adv7162 appendix 7 thermal and environmental considerations the ADV7160/adv7162 is a very highly integrated monolithic silicon device. this high level of integration, in such a small package, inevitably leads to consideration of thermal and envi- ronmental conditions which the ADV7160/adv7162 must op- erate in. reliability of the device is enhanced by keeping it as cool as possible. in order to avoid destructive damage to the de- vice, the absolute maximum junction temperature of 150 c must never be exceeded. certain applications, depending on ambient temperature and pixel data rates may require forced air cooling or external heatsinks. the following data is intended as a guide in evaluating the operating conditions of a particular ap- plication so that optimum device and system performance is achieved. it should be noted that information on package characteristics published herein may not be the most up to date at the time of reading this. advances in package compounds and manufacture will inevitably lead to improvements in the thermal data. please contact your local sales office for the most up-to-date information. power dissipation the diagrams show graphs of power dissipation in watts versus pixel clock frequency for the ADV7160 and adv7162. when using the adv7162 in bypass mode, the pixel mask register should be programmed to 00h to reduce power further. pixel clock frequency ?mhz 2.00 0.50 60 100 140 180 220 1.50 1.25 1.00 0.75 1.75 260 2.25 power dissipation ?watts v aa = +5v v ref = +1.2v t a = +25 c ADV7160 adv7162 note: the "worst case on-screen pattern" corresponds to full-scale transition on each pixel value for every clock edge (00h, ffh, 00h, ...). the "typical on-screen pattern" corresponds to linear changes in tne pixel input (i.e., a black to white ramp). in general, color images tend to approximate this characteristic. typical power dissipation vs. pixel rate package characteristics the tables of thermal characteristics show typical information for the ADV7160 (160-lead plastic power qfp) and ad7162 (160-lead plastic qfp) using various values of airflow. junction-to-case ( q jc ) thermal resistance for this particular part is: q jc (ad7160) = 0.4 c/w q jc (ad7162) = 6.7 c/w (note: q jc is independent of airflow.) heatsinks the maximum silicon junction temperature should be limited to 100 c. temperatures greater than this will reduce long-term device reliability. to ensure that the silicon junction tempera- ture stays within prescribed limits, the addition of an external heatsink may be necessary. heatsinks will reduce q ja as shown in the thermal characteristics vs. airflow table. table a. thermal characteristics vs. airflowCADV7160* air velocity 0 50 100 200 (linear feet/min (still air) q ja c/w no heatsink 25.5 23 21 19 eg&g d10100-28 heatsink 23 20 18 16 thermalloy 2290 heatsink 19 17 15 12 *these figures do not include thermal conduction through the package leads into the pcb. thermal conduction through the leads can provide up to 10 o c/w reduction in q ja . table b. thermal characteristics vs. airflowCadv7162* air velocity 0 50 100 200 (linear feet/min) (still air) q ja c/w no heatsink 37 32 30 28 eg&g d10850-40 heatsink 28 24 22 19 eg&g d10851-36 heatsink 32 24 19 14 *these figures do not include thermal conduction through the package leads into the pcb. thermal conduction through the leads can provide up to 5 o c/w reduction in q ja . thermal model the junction temperature of the device in a specific application is given by: t j = t a + p d ( q jc + q ca ) (1) or t j = t a + p d ( q ja ) (2) where: t j = junction temperature of silicon ( c) t a = ambient temperature ( c) p d = power dissipation (w) q jc = junction to case thermal resistance ( c/w) q ca = case to ambient thermal resistance ( c/w) q ja = junction to ambient thermal resistance ( c/w) package enhancements for ADV7160 the standard pqfp package has been enhanced to a powerquad2 package. this supports an improved thermal performance compared to standard pqfp. in this case, the die is attached to a heat slug so that the power that is dissipated can be conducted to the external surface of the package. this pro- vides a highly efficient path for the transfer of heat to the pack- age surface. the pac kage configuration also provides and efficient thermal path from the ADV7160 to the printed circuit board.
