?9 CXD2453Q description of operation sync signal input pins (hsync, vsync) horizontal and vertical separate sync signals are input to the hsync (pin 29) and vsync (pin 28). the sync signals are compatible with both positive and negative polarity according to serial data settings. (refer to the section on serial data interface for details regarding serial data.) the CXD2453Q supports signals which are shown in the following table. 1024 768 (xga) 1280 1024 (s-xga) 44khz to 69khz 69khz scanning line conversion from 1024 to 768 vertical lines effective dots horizontal scanning frequency 55hz to 85hz roughly 65hz vertical scanning frequency remarks in the case of signals defined by special protocols that do not satisfy the conditions in the diagram below, it may not be possible to obtain a complete display even for the above signals when the image display position is properly set on the lcd panel. this ic does not support interlace signals. hsync enb pcg image display period image display period horizontal blanking period min. 0.17s min. 0.72s master clock input pins (cki1/xcki1, cki2, cki3/xcki3, cki4) and clock selection pins (slck1, slck2) since this ic does not contain a built-in phase comparator, phase comparison is performed externally and a divided clock is input. the 1/n (n is the clock number during 1 horizontal period) frequency divider output is output from the hret (pin 38) for the external phase comparator. the clock input pin consists of two channels for small amplitude differential input (center level: 2.0v, amplitude: ?.4v), and two channels for cmos level input for a total of four channels. these are selected according to the slck1 (pin 26), slck2 (pin 30) and serial data. (1) during normal operation (serial data sllap = 0) all internal circuits of the ic operate with cki1 or cki2. cki1/xcki1 are selected when slck1 = l (pins 3/4, small amplitude differential input), and cki2 is selected when slck1 = h (pin 11, cmos level input). (2) when using scan converter (serial data sllap = 1) this is used when the input signal clock and output signal clock are different such as when performing dot conversion using a scan converter. only the serial data interface and pll counter of the ic internal circuits operate with cki1 or cki2 (clock synchronized with input signal). all other blocks operate with cki3 or cki4 (output signal clock). cki3/xcki13 are selected when slck2 = l (pins 21/22, small amplitude differential input), and cki4 is selected when slck2 = h (pin 13, cmos level input). ?internal frequency divider reset selection pin (slhr) this selects whether reset of the pll counter (loop counter) with hsync is to be enabled or disabled. in the case of performing phase comparison of the hsync and hret pulses with an external phase comparator, the slhr (pin 17) is set to h (reset disabled). when phase comparison and frequency division are performed externally and hret pulses for phase comparison are not used, the slhr is set to l (reset enabled). at this time, the output of each pulse is delayed by approximately 8 clocks as compared with using hret pulses for phase comparison. ?signal inversion type selection pin (slfr) this selects the inversion cycle of the polarity inversion pulse (frp pulse) for ac driving. setting the slfr (pin 19) to h results in field inversion, while setting the slfr to l results in line inversion.
?10 CXD2453Q ?system clear pin (xclr) all internal circuits are initialized when the xclr (pin 78) is l. always make sure to initialize all internal circuits when the power has been turned on. ?serial data interface operating mode and other settings in this ic are performed by serial data. when the power is turned on, all data are set to the default values when the internal circuits are initialized. when the power supply is turned on, the value of sdat is read with the rise of sclk in groups of 16 bits consisting of 8 address bits and 8 data bits as shown in the timing chart below. the data that has been read is enabled by being transferred to the register corresponding to each address 10 clocks after the rise of sclk of the 16th bit. the timing chart and data format during transmission of serial data are as shown below. timing chart sctl (pin 8) sclk (pin 6) sdat (pin 7) address (8 bits) data (8 bits) d15 d14 d13 d12 d11 d10 d9 d8 d7 d6 d5 d4 d3 d2 d1 d0 data format address data d7 d6 d5 d4 d3 d2 d1 d0 settings d15 to d8 f0 f1 f2 f3 f4 f5 f6 f7 f8 f9 fa fb fc fd fe ff plp7 hp7 vp7 ird7 iru7 orp7 ord7 oru7 plp6 hp6 vp6 ird6 iru6 orp6 ord6 oru6 plp5 hp5 vp5 vpol hb ird5 iru5 orp5 ord5 oru5 plp4 hp4 vp4 inv hpol vb ird4 iru4 orrs1 orp4 ord4 oru4 plp3 hp3 vp3 shp3 vscn sllap ird3 iru3 orrs0 orp3 ord3 oru3 plp10 plp2 hp2 vp2 shp2 hscn ird10 ird2 iru10 iru2 orp10 orp2 ord10 ord2 oru10 oru2 plp9 plp1 hp1 vp1 shp1 slxg ird9 ird1 iru9 iru1 orp9 orp1 ord9 ord1 oru9 oru1 plp8 plp0 hp0 vp0 shp0 slsx ird8 ird0 iru8 iru0 orp8 orp0 ord8 ord0 oru8 oru0 pll counter frequency division ratio screen horizontal position screen vertical position cxa2112r s/h control operating mode, etc. operating mode, etc./ iract fall position iract rise position oract reset cycle/ oract division frequency oract fall position oract rise position note) ? don't care
?11 CXD2453Q the following provides a detailed description of each setting. (a) setting of pll counter frequency division ratio this is used to set the frequency division ratio of the 1/n frequency divider (pll counter) for phase comparison. the value of (total number of dots of 1 horizontal period n) ?1 is set with plp10 (msb) through plp0 (lsb). the frequency division ratio can be set up to 2048. only even numbers can be set for the value of n. when it is necessary to set an odd number, use an external frequency divider. in this case, set the value of the frequency division ratio of the pll counter to n-2. the default value is 10100111111 (n = 1344). (b) setting of screen horizontal position the horizontal display start position is set with hp7 (msb) through hp0 (lsb). this setting enables the phase relationships of pulses hst, hck1/2, enb, pcg, prg and clp1/2 as well as the changing positions of vck/frp relative to hsync to change in an interlocked manner. settings can be made in 1 dot units. refer to the timing chart for the relationship between the set value and each pulse position. the default value is 01000100. (c) setting of screen vertical position the vertical display start position is set with vp7 (msb) through vp0 (lsb). this setting enables the phase relationships of signals vst, vck and frp to change relative to vsync in an interlocked manner. settings can be made in 1 line units. refer to the timing chart for the relationship between the set value and each signal. the default value is 00100011. 00000000 and 11111111 are not used. (d) s/h control of cxa2112r this is used to set the sample-and-hold position for the cxa2112r (sample-and-hold driver). inv setting data is output directly from the inv (pin 60). setting data of shp3 (msb) through shp0 (lsb) is reflected as shown below in the shpa through shpd (pins 56 to 59). refer to the specifications of the cxa2112r for details. setting data output output shp3 to shp0 setting data shp3 to shp0 shpa shpb shpc shpd shpa shpb shpc shpd 0000 0001 0010 0011 0100 0101 0110 0111 l h z z l h z z l h l h l h l h l l l l h h h h l l l l h h h h l h z z l h z z l h l h l h l h z z z z z z z z l l l l h h h h 1000 1001 1010 1011 1100 1101 1110 1111 note) z: high impedance state
?12 CXD2453Q (e) setting of operating mode, etc. vpol, hpol: these are used to set the polarity of vsync and hsync. a setting of "1" denotes positive polarity, while a setting of "0" denotes negative polarity. the default values are vpol = 0, hpol = 0. vscn, hscn: these are used to set the vertical and horizontal scanning directions of the lcd panel. vscn = 1 denotes downward scanning, while vscn = 0 denotes upward scanning. hscn = 1 denotes rightward scanning, while hscn = 0 denotes leftward scanning. setting data of vscn is output from the dwn (pin 64), while setting data of hscn is output from the rgt (pin 66). the default values are vscn = 0, hscn = 1. slxg, slsx: these are used to set the input signals (operating mode). this ic has the following three operating modes. the default values are slxg = 0, slsx = 0. operating mode xga- i xga- ii s-xga 0 1 x 0 0 1 slxg slsx note) x: don't care the xga- i mode supports typical xga signals. the xga- ii mode is for xga signals in which there is a low number of dots during a portion of the horizontal blanking period (typically when hsync + back porch is 240 dots or less). select the appropriate operating mode to satisfy the conditions in the diagram on page 6 corresponding to the input signal. in the s-xga mode, 1024 vertical lines are displayed decimating to 768 lines corresponding to the s-xga signal (1280 1024 dots). hb, vb: these are used to switch the number of display dots on the lcd panel. the display is set to 960 dots horizontally when hb = 0, and to 640 lines vertically when vb = 0. the data of each setting is output from the hb (pin 62) and vb (pin 61), respectively. refer to the specifications of the lcx017al for details. the default values are hb = 1, vb = 1. sllap: this is used when the input signal clock and output signal clock differ such as when converting the number of dots using a scan converter. when sllap = 1, only the serial data interface and pll counter of the ic internal circuits operate with cki1 or cki2 (clock synchronized with input signal), while other sections operated with cki3 or cki4 (output signal clock). when sllap = 0, all internal ic circuits operate with cki1 or cki2. the default value is 0. (f) setting of iract fall/rise positions iract pulse a pulse synchronized with hsync of the input signal can be output at any position and width. the fall position of the pulse is set with ird10 (msb) through ird0 (lsb), while the rise position is set with iru10 (msb) through iru0 (lsb). the values of ird0 and iru0 are ignored, and settings are made in 2-dot increments. the setting range is from "0" to (n ?2). the same value cannot be set for ird and iru. refer to the timing chart for the relationship between setting values and pulse positions. the default values are ird10 through ird0 = 00000000000, and iru10 through iru0 = 00010000000.
?13 CXD2453Q (g) setting of oract reset cycle/oract frequency division ratio oract pulses oract pulses are completely identical to iract pulses when serial data sllap = 0, when sllap = 1, they are generated by a dedicated counter (loop counter similar to the pll counter) that operates according to an independent clock (cki3 or cki4) different from the clock synchronized with input signal hsync (cki1 or cki2). since pulses for driving the lcd panel are also generated based on this counter at this time, the lcd panel can be driven based on a clock and cycle that are different from the input signal. oract pulses are synchronized with the cycle of the pulse for driving the lcd panel at this time, and can be output at any position and width. the frequency division ratio of the above dedicated counter is set with orp10 (msb) through orp0 (lsb). the value of (number of counter counts m) ?1 is the actual setting value. only even numbers can be set for m, and settings are made in 2 dot increments. the maximum setting is 2048 counts. this counter is reset with vsync and hsync of a fixed cycle in order to synchronize it with the input signal, the interval of h at which it is to be reset with this hsync is set with orrs1 and orrs0. setting data (orrs1/orrs0) 00 01 10 11 reset cycle every 3h every 4h every 5h every 1h the default values are orrs1 = 1, orrs0 = 1, and orp10 through orp0 = 10100111111. (h) setting of oract fall/rise positions the fall position of the oract pulse is set with ord10 (msb) through ord0 (lsb), while the rise position of the oract pulse is similarly set with oru10 (msb) through oru0 (lsb). the values of ord0 and oru0 are ignored, and settings are made in 2-dot increments. the setting range is from "0" to (m ?2). the same value cannot be set for ord and oru. the relationship between setting values and pulse positions is as indicated below. the default values are ord10 through ord0 = 00000000000, and oru10 through oru0 = 00010000000. hsync oract 8ck 128ck (hsync when reset is applied to counter) (default setting) ord = 000 /hex oru = 080 /hex xhs pulse and xvs pulse the xhs pulse is output over a width of 32 clocks 34 clocks after the fall of the iract pulse when sllap = 0. the pulse has negative polarity. when sllap = 1, the pulse is similarly output over a width of 34 clocks after the fall of the oract pulse. the xvs pulse is vsync latched with the xhs pulse. its polarity is always negative regardless of the polarity of the input vsync. ac driving of lcd panels for no signal when vsync has not been input for a specified period, a judgment of "no signal" is made to allow ac driving of lcd panels even when there is no signal. a vertical start pulse and polarity inverted pulse (frp) are output at a specified cycle. the timing by which a judgment of "no signal" is made and the free running cycle are as indicated below. operating mode free running detection timing (no signal period) and vst cycle during free running all modes 1600h
