DS250DF230: DS250DF230

Part Number: DS250DF230


I'm using DS250DF230 in the design, and I'm doing the PRBS test. The link under test is like this:

322.265625MHz ->  CABLE -> Retimer (10.3125Gbps) -> oscilloscope

I want to use the retimer to generate PRBS. But after I configured the registers, there're no signal outputs. My configuration sequence is shown below:
