9 / 51 page GS1532 Data Sheet 21498 - 8 February 2007 9 of 51 29 SDIN_TDI Synchronous with SCLK_TCK Input CONTROL SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. Serial Data In / Test Data Input Host Mode (JTAG/HOST = LOW) SDIN_TDI operates as the host interface serial input, SDIN, used to write address and configuration information to the internal registers of the device. JTAG Test Mode (JTAG/HOST = HIGH) SDIN_TDI operates as the JTAG test data input, TDI. NOTE: If the host interface is not being used, tie this pin HIGH. 30 SCLK_TCK Non Synchronous Input CONTROL SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. Serial Data Clock / Test Clock. Host Mode (JTAG/HOST = LOW) SCLK_TCK operates as the host interface burst clock, SCLK. Command and data read/write words are clocked into the device synchronously with this clock. JTAG Test Mode (JTAG/HOST = HIGH) SCLK_TCK operates as the JTAG test clock, TCK. NOTE: If the host interface is not being used, tie this pin HIGH. 32 BLANK Synchronous with PCLK Input CONTROL SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. Used to enable or disable input data blanking. When set LOW, the luma and chroma input data is set to the appropriate blanking levels. Horizontal and vertical ancillary spaces will also be set to blanking levels. When set HIGH, the luma and chroma input data pass through the device unaltered. 33, 68 CORE_GND – Power Ground connection for the digital core logic. Connect to digital GND. 34 F Synchronous with PCLK Input CONTROL SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. Used to indicate the ODD / EVEN field of the video signal when DETECT_TRS is set LOW. The device will set the F bit in all outgoing TRS signals for the entire period that the F input signal is HIGH (IOPROC_EN/DIS must also be HIGH). The F signal should be set HIGH for the entire period of field 2 and should be set LOW for all lines in field 1 and for all lines in progressive scan systems. The F signal is ignored when DETECT_TRS = HIGH. Table 1-1: Pin Descriptions (Continued) Pin Number Name Timing Type Description |
