Part Number: DP83TC812R-Q1 Tool/software: question:The reading of PHY id is 0xFFFFFFFF, and the values of VDD are ok. May I ask what other hardware circuits may cause that the phy id cannot be read ? Or other reasons？
The hardware schematic diagram is…
Part Number: DP83TC812R-Q1 Tool/software: Hello experts,
What is the power supply for DP83TC812R-Q1? (1) Rise Condition
I think several power supplies are input to the Ethernet PHY.
Is it correct that they need to be turned on at the same time?
(2)…
Part Number: DP83TC812R-Q1 Tool/software: Hello Team, customer see failures in the Ethernet Compliance Test which seems that the root cause is our PHY. Please could you comment on it. Many Thanks Josef

Part Number: DP83TC812R-Q1 Tool/software: Hi TI team,
Would you please provide the steps of putting DP83TC812R into sleep mode by local sleep operation ?
I check this video on youtube, but I can not reproduce same phenomenon .
In my test case, one SoC…
Part Number: DP83TC812R-Q1 Tool/software: Hi TI team,
Would you please provide the test flow of force sleep mode ? When I write 0x000C to register 0x0444, the INH is not released.
INH is an open drain (high polarity) output pin which indicates whether…
