Hi e2e

I used the DS250DF410EVM as a PRBS Checker,how does it worked of DS250DF410 can checked the signal in is PRBS7,PRBS15 or PRBS31.

there has no no reference clock in for channel 2 or channel 3,but it can lock to the signal in and worked as a PRBS Checker?

thank you.

Greetings,

1). DS250DF410 can automatically check incoming PRBS pattern and indicates if it is PRBS7. PRBS31, and etc.

2). Externally - through 100-ohm input of the 2nd channel- we should connect a differential cable or trace to the input of the PRBS checker channel.

Please below note an E2E case discussing this in more details.
