DS90LV027A: AC couple the outputs

adomino

Part Number: DS90LV027A

Is it ok to AC couple the outputs of the DS90LV027A? In the datasheet, it says that AC or unterminated configurations are not allowed. But if the LVDS RX in the system has integrated 100Ohm termination and internal biasing, then it would be ok to AC couple the outputs, correct?

As long as the DS90LV027A output is not held at a static state it is okay to AC couple the LVDS outputs. In normal LVDS links, the output Tx provides the common mode for the differential signal. In this case the input will be isolated from the output common mode so it will need to be self biased to an appropriate level.
