When an external clock (LVCMOS) oscillator is used as the clock source for the processor and the EPHY, a single oscillator is recommended for the processor and the EPHY. It is recommended to use two-output phase aligned buffer for the processor and the EPHY. Be sure to connect XO of the processor as per the device-specific data sheet recommendations. Refer device-specific SK for implementation.
Additionally, verify if the crystal XO of the EPHY has connection recommendations to be followed.
