Part Number: DP83822IF
My customer is using our DP83822. They use FPGA to realize Mac function. Below is the schematic for your check, 4pcs/board.
RP4032-1-001 _ p04-PHY.pdf
They use RMII and 50MHz osc reference.
The problem is that:
1. When debugging DP83822, it was found that the RXDV, RXD[1:0] timing from PHY may have some problem: RXD[1:0] signal will come out 7 clk(about 140ns) after RXDV signal. See below timing picture:
2. These is sudden change at the end of the RXDV's message, see below:
Customer is pushing the pp schedule, so can you help check above 2 questions, thanks a lot!
