DS90UB948-Q1: Repeat Mode Configuration for FPD-Link III Repeater using DS90UH947-Q1 and DS90UB948-Q1

Hello Experts,

I need help because I don't know how exactly I should configure DS90UH947 and DS90UB948.

My application is a repeater which has one receiver and one transmitter. In the meantime the repeater drive a local display through dual channel LVDS.

Q1. In this scenario, should I set repeat mode ( by selecting low 4 options using MODE_SEL1 )?

Q2. Datasheet says repeat mode has to be set for repeater. As transmitter of repeater may treat the LVDS input as any LVDS source, why it needs repeater mode?

Q3. How different will the transmitter and receiver behave between repeater mode =0 and =1?

Thanks for your time!

Best Regards,

Michael
