TTL level input
Positive LVDS differential data output
Negative LVDS differential data output
TTL level clock input. The rising edge acts
as data strobe. Pin name TxCLK IN
Positive LVDS differential clock output
Negative LVDS differential clock output
TTL level input. Assertion (low input) TRI-
STATEs the clock and data outputs, ensur-
ing low current at power down.
