Hi Team,
My customer designed their board and is evaluating DS250DF230 (Front-Port Ingress, Module-to-Host).
He confirmed CDR Lock (Channel Register Reg0x02=0xD8) however subsequent stage BERT shows "Sync-Loss" in this case.
If he set Channel Register Reg0xA5[7:5] from "001" to "000", he confirmed the issue doesn't occurred.
Is it possible case?
On the other hand, he set Channel Register Reg0x3D[7] from "0" to "1" then confirmed the issue doesn't occurred when Reg0xA5[7:5]=001.
Should Reg0x3D[7] be set to "1"?
If you need waveform, please send private message then we can share it.
Best Regards,
Yaita
