DS90UB960-Q1: layout question consult

Part Number: DS90UB960-Q1

Hi Team,

As for 960's layout, here are two questions would like to consult with you.

1. Customer use COAX mode. Do the input RIN+ and RIN- of FPD LINK III need to use differential lines? The 960 specification requires RIN+ and RIN- to be routed according to the 3W principle, but before customer drew the 933 and 934 PCBs, there was a requirement to use differential lines.
2. Should the 49.9Ω termination resistor of RIN- be placed close to the 960or the connector?
Thank you.
