Part Number: DP83TC812S-Q1 Hi, TI
We're experiencing a link down issue.
Register 0x871 shows that the current SQI value is 0, register 0x1 shows that the current state is Link up, and it is currently not able to communicate with the peer.
Part Number: DP83TC812S-Q1 Hi team,
My customer uses 812s in their system and the project is in mass production status now. They found a board that has fault while running. The 0x60A register value was 0x136, which means SGMII link down. The other register…
Part Number: DP83TC812S-Q1 Hi TI Expert,
Could you explain more details about the below table 8-12 in DP83TC812S-Q1 datasheet under RGMII mode?
We notice the TX_CTRL pin will keep high during transmission.
From the datasheet, it seems that the TX_CT…
Part Number: DP83TC812S-Q1 hello
Could you explain the possible reason of link up 0x01=0x0065 with SQI reg871=0?
1. Constant reading for tens of times with stable reading when ethernet communication doesn't work well
2. After 30min, SQI reading turns…
