8 / 61 page GS9092A GenLINX® III 270Mb/s Serializer for SDI and DVB-ASI Final Data Sheet 34715 - 5 February 2013 8 of 61 16CS_TMS Synchronous with SCLK_TCK Input CONTROL SIGNAL INPUT Signal levels are LVCMOS / LVTTL compatible. Chip Select / Test Mode Select Host Mode (JTAG/HOST = LOW): CS/TMS operates as the host interface chip select, CS, and is active LOW. JTAG Test Mode (JTAG/HOST = HIGH): CS/TMS operates as the JTAG test mode select, TMS, and is active HIGH. Note: If this pin is unused it should be pulled up to VCC_IO. 17 SCLK_TCK Non Synchronous Input CONTROL SIGNAL INPUT Signal levels are LVCMOS / LVTTL compatible. Serial Data Clock / Test Clock. All JTAG / Host Interface address and data is shifted into / out of the device synchronously with this clock. Host Mode (JTAG/HOST = LOW): SCLK_TCK operates as the host interface serial data clock, SCLK. JTAG Test Mode (JTAG/HOST = HIGH): SCLK_TCK operates as the JTAG test clock, TCK. Note: If this pin is unused it should be pulled up to VCC_IO. 18, 48 CORE_GND Non Synchronous Input Power Ground connection for digital logic blocks. Connect to GND. 19 SDOUT_TDO Synchronous with SCLK_TCK Output CONTROL SIGNAL INPUT Signal levels are LVCMOS / LVTTL compatible. Serial Data Output / Test Data Output Host Mode (JTAG/HOST = LOW): SDOUT_TDO operates as the host interface serial output, SDOUT, used to read status and configuration information from the internal registers of the device. JTAG Test Mode (JTAG/HOST = HIGH): SDOUT_TDO operates as the JTAG test data output, TDO. 20 SDIN_TDI Synchronous with SCLK_TCK Input CONTROL SIGNAL INPUT Signal levels are LVCMOS / LVTTL compatible. Serial Data Input / 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 this pin is unused it should be pulled up to VCC_IO. 21, 29, 43 IO_VDD Non Synchronous Input Power Power supply for digital I/O. For a 3.3V tolerant I/O, connect pins to either +1.8V DC or +3.3V DC. For a 5V tolerant I/O, connect pins to a +3.3V DC. Note: For power sequencing requirements please see Device Power Up on page 56. 22, 27 RSV – – Reserved. Do Not Connect.
