TMS320F28388D: Ethernet PHY clock source

Hi,

At present for TMS320F28388D control card if you see the schematic it uses a fan-out clock buffer to generate the 25MHz phy clocks for Ethernet, Ethercat and device clock input from an oscillator. (pg 3 MCU063B(002)_Sch.PDF)

So if the load on clock does not effect other you can use XCLKOUT or ECAT_PHY_CLK.
