TMS320F28388D: Ethernet PHY clock source

Part Number: TMS320F28388D


Could XCLKOUT or ECAT_PHY_CLK be used as the clock source for Ethernet PHY? Thank you.


  • 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.
