Table Legend:

1. DP83TC811 - 10% tolerance components are recommended.

1. DP83TC812 - 10% tolerance components are recommended.

DP83TC812 - If VDDIO is separate from VDDMAC then additional ferrite bead and 0.47 μF capacitor will be required on VDDIO.

DP83TC814 - 10% tolerance components are recommended.

DP83TC814 - If VDDIO is separate from VDDMAC then additional ferrite bead and 0.47 μF capacitor will be required on VDDIO.
