Hello,
Do you have recommendation for unused channel inputs, can we left them floating or is it better to ground them with 50 Ohm?
Best regards,
Tristan

Hi Tristan,
It is preferred to AC couple and then 50-ohm to ground. Un-used input would have its signal detect off and this powers down CDR if this input is selected. It is a good design practice to terminate un-used inputs to prevent any potential cross coupling.
