Other Parts Discussed in Thread: DS90UB914A-Q1, DS90UB913A-Q1
Generally, the DS90UB913A EVM GPO0 and GPO1 LEDs are lit. However, when I connect the serializer to a custom board (with 9V power over coax from the deserializer side), GPO0 and GPO1 are not lit.
What do these LEDs indicate? I have the serializer EVM switches in the default setting and have not written down any settings over I2C (i.e. should be default register values).
I am getting a LOCK signal and data/clock toggles on the deserializer side, so things seem to be working despite the LEDs.
