- TTL input signals should have a 5 V unidirectional TVS device
on them
- TTL output signals should have a 5 V unidirectional TVS device
on them
- BNC Analog Inputs:
- LOG_VIDEO signal (AMUX0) is a 0.5 to 2.5 analog signal with
very low frequency/DC characteristics
- Spare test input (AMUX1) is connected to resistive network and
capacitor to allow flexibility in maximum signal. As configured,
it will accept 3V input low frequency signal.
