PRBS Generator and Checker at Lower Speed - 1Gbps

Other Parts Discussed in Thread: DS125DF1610

Hi TI Support Team,

I'd like to design a board that can generate PRBS31 patterns at 1Gpbs speed.

And the PRSB checker can receive the pattern and check the results.

The purpose is to make sure that 24pairs of differential traces on DUT have no problem.

It is known that PRBS generator and checker cannot be the same chip.

Would you please recommend any suitable chips for this? Thank you.

Hi,

You may consider the DS125DF1610 retimer.

Hi Rodrigo,

Thanks for the recommendation.

I have 2 questions that need your help:

1. May I know how to decide the data rate?

2. According to the BERT Board Reference Design, Quad 0 and Quad 3 are used as pattern checkers whereas 1 and 2 are used as pattern generators.

May I know if the test plan below is workable?

Quad 1(PRBS31) -> RF4 Trace -> Quad 0

Quad 2(PRBS31) -> RF4 Trace -> Quad 3

The pattern generator and checker are using the same chip.

Thank you for your help!
