Not Connected. Leave these pins floating. Do not connect to any supply, ground or logic level.
Non-inverting and Inverting serial externally terminated inputs.
Non-inverting and inverting serial unterminated data outputs to coaxial cable.
Non-inverting and inverting serial unterminated data outputs to coaxial cable.
A high mutes SDO2/SDO2 outputs, low enables SDO2/SDO2.
A high mutes SDO1/SDO1 outputs, low enables SDO1, SDO1.
Input control signal to change the output slew rate.
SD/HD = High: Slow output slew rate for SD-SDI rate (143–540 Mbps).
SD/HD = Low: Fast output slew rate for HD and 2xHD-SDI rate (1485 Mbps).
