DP83822I: No TX_CLK and RX_CLK output under MII Mode

Part Number: DP83822I

Tool/software:

Dear Team,

My customer is evaluating the DP83822I on their board. MII Mode is set by Bootstrap, AVD=VDDIO=3..3V power up and 25-MHz reference clock is inputted, however TX_CLK and RX_CLK are not outputted from the PHY to the MAC of Processor.

What are the possible factors for this phenomenon?

Best Regards,

Koshi Ninomiya
