DP83867E: Looking for abs max vin specification for XI

Part Number: DP83867E

What are input constraints for XI when driven externally? Can XI start prior to VDD (as plots imply)

XI is not listed in abs max table for inputs.

Thanks,

Hi Wade,

XI can be driven directly with 1.8V external clock source, and with capacitor divider for 2.5V/3.3V. Refer to section 9.2.1.2 of datasheet for more details.

The XI clock should start prior to VDD.
