Description
TTL level input. This includes: 8 Red, 8 Green, 8 Blue, and 4 control lines — FPLINE,
FPFRAME and DRDY (also referred to as HSYNC, VSYNC, Data Enable).
Positive LVDS differentiaI data output.
Negative LVDS differential data output.
TTL Ievel clock input. The falling edge acts as data strobe. Pin name TxCLK IN.
Programmable strobe select (See Table 1).
Positive LVDS differential clock output.
Negative LVDS differential clock output.
TTL level input. Assertion (low input) TRI-STATES the outputs, ensuring low current at power
down. See Applications Information section.
Power supply pins for TTL inputs.
Ground pins for TTL inputs.
Power supply pin for PLL.
Ground pins for PLL.
Power supply pin for LVDS outputs.
