    Hello,

    Overall, the schematic looks good. Below is my only comment:

    1. MDC does not need the pullup resistor and capacitor. The MDC pin should just be a straight connection to the header. However, the MDIO pin needs a 1.5k pullup resistor (the capacitor is not needed).

    I cannot comment on the TJA1101 part of the schematic since that is not a TI ethernet device.

    Regards,
