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 from "0" to "1" then confirmed the issue doesn't occurred when Reg0xA5[7:5]=001.
Should Reg0x3D be set to "1"?
If you need waveform, please send private message then we can share it.
