Figure 8 shows the test set-up for the GS9000D operating from a VDD supply of +5 volts. The differential pseudo ECL inputs for DATA and CLOCK (pins 5,6,7 and 8) must be biased between +3.0 and +4.05 volts. In the application circuit shown in Figure 11, these inputs can be directly driven from the outputs of the GS7025 Reclocking Receiver with their resistor values set as shown. shown . In other cases, such as true ECL level driver outputs, two biasing resistors are needed on the DATA and CLOCK inputs and the signals must be AC coupled. It is critical that the decoupling capacitors connected to pins 12,13 and 18 are chip types and are located as close as possible to the device pins. The critical high speed inputs, such as Serial Data (pins 5 and 6) and Serial Clock (pins 7 and 8), are located along one side of the device package to maintain very short interconnections when interfacing with the GS7025 Receiver. 6 GENNUM CORPORATION 18784 - 2 ** Locate the three 0.10µF decoupling capacitors as close as possible to the corresponding pins on the GS9000D.

The Parallel Data bits PD0 through PD9 and the Parallel Clock can be observed on an oscilloscope or fed to a logic analyzer. To directly drive parallel inputs to receiving equipment, such as monitors or digital to analog converters, these outputs can be fed through a suitable TTL to ECL converter. The HSYNC output toggles to indicate the presence of the TRS on the falling edge of PCLK, one data symbol prior to the output of the first word in the TRS. In the following diagram, data is indicated in 10-bit Hex. PCLK PDN In operation, the HSYNC output from the GS9000D decoder toggles on each occurrence of the timing reference signal (TRS). The state of the HSYNC output is not significant, but the time at which it toggles is significant. 4ƒSC DATA STREAM T R S ACTIVE VIDEO & H BLANKING E A V H BLNK T R S ACTIVE VIDEO & H BLANKING XXX 3FF 000 000 XXX XXX 3FF 000 000 XXX HSYNC Fig. 10 Operation of HSYNC with Respect to PCLK T R S HSYNC OUT 4:2:2 DATA STREAM S A V ACTIVE VIDEO E A V H BLNK S A V HSYNC OUT Fig. 9 Operation of HSYNC Output 7 GENNUM CORPORATION 18784 - 2 TYPICAL APPLICATION CIRCUIT - Adjustment Free Multi-standard Serial To Parallel Convertor Vcc 8.2nH 100nF Vcc 1uF Serial Data Output 1uF 100nF 75 5 VEE GS9000D 6 SDI 90.9 SDI 90.9 VCC 7 GS9028 4 RSET 3 100nF VEE 2 SDO 1 SDO 37.5 8 75 Vcc 59 Vcc LOCK Vcc Vcc Vcc 22k CD Vcc 4.75k 150 150 CLK_EN 150 CLK_EN Vcc Vcc 100nF Vcc GS9000D 8 21 10 20 11 NC 19 12 Vcc 270 13 14 15 16 17 100 PD7 PD6 100 PD5 100 PD4 100 PD3 100 PD2 100 PD1 100 100 18 Vcc 100nF NC Vcc 22 9 VDD 22 SSC VSS 21 Vcc 100nF 100nF VCC RVCO 365 68k 22nF Vcc 20 CBG VEE 15nF RVCO_RTN LFS LF- VEE 1.8k 19 NC 23 100 18 SS0 24 PCLK 17 VEE 100 26 6 PD0 16 LF+ AGC+ 100nF 100pF VCC 100k 15 SS1 27 7 100nF 23 14 SCO PD9 100nF 11 SCI PD8 24 SCO 28 25 SCE 10 SCI 1 SWC 25 VEE 2 100 5 VDD 26 9 SDI VDD 8 SDO 3 HSYNC 27 SDI VSS 28 4 SDO SWF 29 GS7025 (2) VSS 30 VEE 90.9 31 90.9 34 4 13 3k3 100 VEE VCC CLK_EN VEE 35 3 12 Pot 36 7 VCC AGC- 37 32 6 VEE Vcc 38 33 5 SDI CD_ADJ 39 COSC 10n 4.7nF 100nF 15nH (1) 75 Vcc LOCK 75 VEE SDI 37.5 40 2 VCC 10n 41 1 DDI VCC_75 75 SSI/CD 100nF Serial Data Input 42 A/D DDI Vcc 43 MOD VCC 44 OEM_TEST Vcc Vcc * 3.3pF NOTE: Value of SDO and SCO pull-up resistors is 90.9Ω ± 1% (1) Typical value for input return loss matching (2) The GS7025 can be replaced by either the GS9025A or GS9035A for applications at data rates less then 270Mb/s or when equalization is not required Fig. 11 GS9000D and GS7025 INTERCONNECTIONS Figure 11 shows an application of the GS9000D in a 270Mb/s serial to parallel converter. This circuit uses the GS7025 Serial Digital Receiver. For datarates below 270Mb/s the GS9025A can be used. If cable equalization is not required the GS7025 or GS9025A may be replaced with a GS9035A Reclocker IC. The GS9028 Cable Equalizer allows a serial loop through after the reclocker. 8 GENNUM CORPORATION 18784 - 2 SYNC WARNING FLAG OPERATION GS9000D Each time HSYNC is not correctly detected, the Sync Warning Flag output (pin 3 ) will go HIGH. The RC network connected to the Sync Warning Control input (pin 15) sets the number of sync errors that will cause the SWF pin to go HIGH. The component values of the RC network shown in Figure 12 set the SWF error rate to approximately one HSYNC error in 10 lines. These component values are chosen for optimum performance of the SWF pin, and should not be adjusted. Typically, HSYNC errors become visible on a monitor before the SWF provides an indication of HSYNC errors. As a result, the SWF function can be used in applications where the detection of significant signal degradation is desired. A high SWF goes low when the input error rate decreases below the set rate. A small amount of hysteris in the comparator ensures noise immunity.
