TMDSCNCD28388D: EtherCAT PHY clock source?

Hi Champs,

I know the default setting of the EtherCAT PHY clock source in F2838x controlCARD revB is 25Hz distributed from one external oscillator so that helps reduce the jitter of the sync signal. But, my customer is considering ESC_PHY_CLK (GPIO154, 48) for each EtherCAT PHY. I could not find in the datasheet if ESC_PHY_CLK signal can meet the EtherCAT specification.

If the external oscillator connected with MCU meets the EtherCAT requirements, does ESC_PHY_CLKL fully work with EtherCAT specification?

Thanks,
Steve
