Hi Sir,
My cusotmer use DP83848J on their video conversion product. They have 1/10 failure rate on their MP products with differet questions:
1. Abnormal AN1 signal: they test their boards but sometimes AN1 signal show 10Mbps status only.
2. AN0 signal unstable: the status LED is flashing.
3. Some times they can't ping their device correctly. Need 3 or 4 retest and get response.
Is there any point they can check to test their boards? Or is there any design issue as attached schematic? Thanks for your kindly help.
Best regards,
Gary Teng
