Input control signal for setting the single-ended output swing amplitude.
Higher output swing levels or reduced variations with a ±1% tolerance external
resistor.
For 800mVp–p single-ended, a 750Ω ±1% resistor to AV
Non-inverting and Inverting serial externally terminated inputs.
Non-inverting and inverting serial unterminated data outputs to coaxial cable.
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.
A low disables the SDO/SDO outputs.
A high enables the SDO/SDO outputs.
