2.4.5 EtherCAT PHY Clock Selection

The controlSOM provides two EtherCAT PHY clock outputs, ECAT_PHY0_CLK and ECAT_PHY1_CLK. By default, these clocks are sourced from a 25-MHz BAW oscillator (Y1). These clocks can also be sourced from the ESC_PHY_CLK on the F29H85x device. An optional resistor configuration is included source for the EtherCAT PHY clocks from the GPIO54/ESC_PHY_CLK output on the F29H85x device. To enable this option, follow the instructions on Table 2-9. Refer to the F29H85x and F29P58x Real-Time Microcontrollers data sheet for more information on ESC_PHY_CLK.
