Part Number: DP83TC812S-Q1 Hi Team,
My customer is KOSTAL, they used DP83TC812S-Q1 on JMC's ZCU project.
Since 100M PHY is a reserved function in this project, DP83TC812S-Q1 may not be used on some models. Therefore, in their design, they plan to…
Part Number: DP83TC812S-Q1
Link status is shown in register 0x1 bit[2]. Link failing to show as up can be caused by many issues. Please see the following debug guide which walks through several of the possible causes and fixes. Specifically see section…
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.
After…
Part Number: DP83TC812S-Q1 Reducing the slew rate of MAC interface IOs can provide improvement in EMC emissions for some frequencies. This can be done using register 0x456.
0x456 bits [5] and [0] control the impedance of the RX and TX MAC interface pads…
Hi Avtar,
Thank you for your prompt reply.
Avtar Dhaliwal said: In regards to your first question, yes an ethernet controller will be needed as the MAC layer is necessary.
Do you have any recommendations, among TI's ethernet controllers for such an application…
Part Number: DP83TC812R-Q1 Hi Ethernet team,
My customer use DP83TC812 and they find that there is sawtooth wave at DP83TC812 physical layer (DP/DN) in PMA mode1. Do you have ever meet this issue?
1. Could you please help to analyze the reason?
2.Please…
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: TDA4AL-Q1 Hi experts,
We are using DP83TC812 PHY via RGMII, our strap pin setting is 0x8C.
We update the driver from below link:
DP83TC812S-Q1: validation of sgmii failed - Interface forum - Interface - TI E2E support forums
Now we can…
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…
