gs1532 data sheet 21498 - 8 february 2007 24 of 51 3. detailed description 3.1 functional overview the gs1532 is a multi-rate serializer with an integrated cable driver. when used in conjunction with the exter nal go1555/go1525* voltage controlled oscillator, a transmit solution at 1.485gb/s, 1.485 /1.001gb/s or 270mb/s is realized. the device has three different modes of operation which must be set by the application layer through external device pins. when smpte mode is enabled, the device w ill accept 10-bit multiplexed or 20-bit demultiplexed smpte compliant data at both hd and sd signal rates. the device?s additional processing features are also enabled in this mode. in dvb-asi mode, the gs1532 will accept an 8-bit parallel dvb-asi compliant transport stream on its upp er input bus. the serial output data stream will be 8b/10b encoded and stuffed. the gs1532?s third mode allows for the serializing of data not conforming to smpte or dvb-asi streams. the provided serial digital outputs feat ure a high impedance mode, output mute on loss of parallel clock and adjustable signal swing. the output slew rate is automatically controlled by the sd/hd setting. in the digital signal processing core, several data processing functions are implemented including smpte 352m and edh data packet generation and insertion, and automatic video standards de tection. these featur es are all enabled by default, but may be individually disabled via internal registers accessible through the gspi host interface. finally, the gs1532 contains a jtag interface for boundary scan test implementations. *for new designs use go1555 3.2 parallel data inputs data inputs enter the device on the rising edge of pclk as shown in figure 3-1 . the input data format is defined by the setting of the external sd/hd , smpte_bypass and dvb_asi pins and may be presented in 10-bit or 20-bit format. the input data bus width is controlled independently from the internal data bus width by the 20bit/10bit input pin.
gs1532 data sheet 21498 - 8 february 2007 25 of 51 figure 3-1: pclk to data timing 3.2.1 parallel input in smpte mode when the device is operating in smpte mode, (see smpte mode on page 27 ), both sd and hd data may be presented to the input bus in either multiplexed or demultiplexed form depending on the setting of the 20bit/10bit input pin. in 20-bit mode, (20bit/10bit = high), the input data format should be word aligned, demultiplexed luma and chroma data. luma words should be presented to din[19:10] while chroma wo rds should occupy din[9:0]. in 10-bit mode, (20bit/10bit = low), the input data format should be word aligned, multiplexed luma and chroma data. the data should be presented to din[19:10]. din[9:0] will be high im pedance in this mode. 3.2.2 parallel input in dvb-asi mode when operating in dvb-asi mode, (see dvb-asi mode on page 29 ), the gs1532 automatically configures the input port for 10-bit operation regardless of the setting of the 20bit/10bit pin. the device will accept 8-bit data words on di n[17:10] such that din17 = hin is the most significant bit of the encoded transp ort stream data and din10 = ain is the least significant bit. in addition, din19 and din18 will be conf igured as the dvb-asi control signals inssyncin and kin respectively. see dvb-asi mode on page 29 for a description of these dvb-asi specific input signals. din[9:0] will be high impedan ce when the gs1 532 is operating in dvb-asi mode. 3.2.3 parallel input in data-through mode when operating in data-through mode, (see data-through mode on page 29 ), the gs1532 passes data presented to the parallel input bus to the serial output without performing any encoding or scrambling. the input data bus width acc epted by the device in this mode is controlled by the setting of the 20bit/10bit pin. pclk din[19:0] data c ontrol signal input t is t ih
gs1532 data sheet 21498 - 8 february 2007 26 of 51 3.2.4 parallel input clock (pclk) the frequency of the pclk input signal re quired by the gs1532 is determined by the input data format. table 3-1 below lists the possible input signal formats and their corresponding parallel clock rates. no te that dvb-asi inpu t will always be in 10-bit format, rega rdless of the setting of the 20bit/10bit pin. table 3-1: parallel data input format input data format din [19:10] din [9:0] pclk control signals 20bit/ 10bit sd/ hd smpte_bypass dvb_asi smpte mode 20bit demultiplexed sd luma chroma 13.5mhz high high high low 10bit multiplexed sd luma / chroma high impedance 27mhz low high high low 20bit demultiplexed hd luma chroma 74.25 or 74.25/ 1.001mhz high low high low 10bit multiplexed hd luma / chroma high impedance 148.5 or 148.5/ 1.001mhz low low high low dvb-asi mode 10bit dvb-asi dvb-asi data high impedance 27mhz high high low high low high low high data-through mode 20bit demultiplexed sd data data 13.5mhz high high low low 10bit multiplexed sd data high impedance 27mhz low high low low 20bit demultiplexed hd data data 74.25 or 74.25/ 1.001mhz high low low low 10bit multiplexed hd data high impedance 148.5 or 148.5/ 1.001mhz low low low low
gs1532 data sheet 21498 - 8 february 2007 27 of 51 3.3 smpte mode the gs1532 is said to be in smpte mode when the smpte_bypass pin is set high and the dvb_asi pin is set low. in this mode, the parallel data will be scrambled acco rding to smpte 259m or 292m, and nrz-to-nrzi encoded prior to serialization. 3.3.1 internal flywheel the gs1532 has an internal flywheel which is used in the generation of internal / external timing signals, and in autom atic video standards detection. it is operational in smpte mode only. the flywheel consists of a number of coun ters and comparators operating at video pixel and video line rates. these counters maintain information about the total line length, active line length, total number of lin es per field / frame and total active lines per field / frame for the received video standard. when detect_trs is low, the flywheel will be locked to the externally supplied h, v, and f timing signals. when detect_trs is high, the flywheel will be locked to the embedded trs signals in the para llel input data. both 8-bit and 10-bit trs code words will be identified by the device. the flywheel 'learns' the video standard by timing the horizontal and vertical reference information supplied a the h, v, and f input pins, or contained in the trs id words of the received video data. full synchronization of the flywheel to the received video standard therefore requires one complete video frame. once synchronization has be en achieved, the fl ywheel will continue to monitor the received trs timing or the supplied h, v, and f timing information to maintain synchronization. 3.3.2 hvf timing signal extraction as discussed above, the gs1532's internal flywheel may be locked to externally provided h, v, and f signals when detect_trs is set low by the application layer. the h signal timing should also be configured via the h_config bit of the internal ioproc_disable register as either ac tive line based blanking or trs based blanking, (see packet generation and insertion on page 32 ). active line based blanking is enabled when the h_config bit is set low. in this mode, the h input should be high for the entire horizontal blanking period, including the eav and sav trs words. this is the default h timing assumed by the device. when h_config is se t high, trs based blanking is enabled. in this case, the h input should be set high for the entire ho rizontal blanking period as indicated by the h bit in the associated trs words.
gs1532 data sheet 21498 - 8 february 2007 28 of 51 the timing of these signals is shown in figure 3-2 . figure 3-2: h, v, f timing h:v:f timing - hd 20-bit input mode pclk luma data out chroma data out h xyz (eav) 000 000 3ff xyz (eav) 000 000 3ff v f xyz (sav) 000 000 3ff xyz (sav) 000 000 3ff h;v:f timing at sav - hd 10-bit input mode 000 000 3ff 3ff xyz (sav) 000 000 xyz (sav) pclk h v f h:v:f timing at eav - hd 10-bit input mode pclk 000 000 3ff 3ff xyz (eav) 000 000 xyz (eav) multiplexed y/cr/cb data out h v f multiplexed y/cr/cb data out h:v:f timing - sd 20-bit input mode pclk chroma data out luma data out h 000 3ff xyz (eav) 000 v f 000 3ff xyz (sav) 000 h:v:f timing - sd 10-bit input mode multiplexed y/cr/cb data out pclk h v f xyz (eav) 000 000 3ff xyz (sav) 000 000 3ff h signal timing: h_config = low h_config = high

gs1532 data sheet 21498 - 8 february 2007 42 of 51 the integrated cable driver uses a separate power supply of +1.8v dc supplied via the cd_vdd and cd_gnd pins. 3.9.1 output swing nominally, the voltage swing of the serial digital output is 800mvp-p single-ended into a 75 ? load. this is set exte rnally by connecting the rset pin to cd_vdd through 281 ? . the output swing may be decreased by increasing the value of the rset resistor. the relationship is approximated by the curve shown in figure 3-5 . alternatively, the serial digital outpu t swing can drive 800mvp-p into a 50 ? load. since the output swing is reduced by a factor of approximately one third when the smaller load is used, the rset resistor must be 187 ? to obtain 800mvp-p. figure 3-5: serial digi tal output swing 3.9.2 serial digital output mute the gs1532 will automa tically mute the serial digi tal output when the locked output signal is low. in this case, the sdo and sdo signals are set to a constant voltage level. 3.10 gspi host interface the gspi, or gennum serial peripheral interface, is a 4-wire interface provided to allow the host to enable additional features of the device and /or to provide additional status information through configuration registers in the gs1532. the gspi comprises a serial data inpu t signal sdin, serial data output signal sdout, an active low chip select cs , and a burst clock sclk. the burst clock must have a duty cycle between 40% and 60%. because these pins are shared with the jtag interface port, an additional control signal pin jtag/host is provided. when jtag/host is low, the gspi interface is enabled. 50 ? load 300 400 500 600 700 800 900 1000 250 300 350 400 450 500 550 600 650 700 rset( ? ) ? v sdo (mvp-p) 200 75 ? load
gs1532 data sheet 21498 - 8 february 2007 43 of 51 when operating in gspi mode, the sclk, sdin, and cs signals are provided by the host interface. the sdout pin is a high-impedance output allowing multiple devices to be connected in parallel and selected via the cs input. the interface is illustrated in the figure 3-6 below. all read or write access to the gs1532 is initiated and terminated by the host processor. each access always begins with a 16-bit command word on sdin indicating the address of the register of interest. this is followed by a 16-bit data word on sdin in write mode, or a 16-bit data word on sdout in read mode. figure 3-6: gennum serial peripheral interface (gspi) 3.10.1 command word description the command word is transmitted msb firs t and contains a read/write bit, nine reserved bits and a 6-bit register address. set r/w = '1' to read and r/w = '0' to write from the gspi. command words are clocked into the gs1532 on the rising edge of the serial clock sclk. the appropriate chip select signal, cs , must be asserted low a minimum of 1.5ns (t 0 in figure 3-9 and figure 3-10 ) before the first clock edge to ensure proper operation. each command word must be followed by only one data word to ensure proper operation. figure 3-7: command word figure 3-8: data word sclk cs sdout sdin sclk cs sdin sdout application host gs1532 r/w rsv rsv rsv a0 a1 a2 a3 a4 a5 rsv rsv rsv rsv rsv rsv msb lsb d15 d14 d13 d12 d0 d1 d2 d3 d4 d5 d6 d7 d8 d9 d11 d10 msb ls b
