Other Parts Discussed in Thread: DS125DF1610

Hi,

I'd like to use TI's DS125DF1610 (16-ch retimer), and want to use this ic as no adaption mode.

Can you share the TI's recommanded register values for 10.3125 Gpbs at ADAPT_MODE 00?

for your information, reference clock is 25MHz, no cross point.

    We typically only recommend adapt mode 0 for applications where the retimer pre-channel insertion loss is very low. For such a scenario, the settings below apply:
