Hello Muktha,

Your question has been assigned to the correct engineer, please expect a slight delay in response.

Muktha,

For the TXC, the internal delay is always enabled, and for the RXC, it will have to be externally delayed (either with the PHY side Internal delay or board delay).

Also, the board propagation delay mismatch must be within 50ps, as recommended.

All the setup and hold time must be simulated to ensure the RGMII specs are met.
