DP83867IR: Oscillator Voltage

Part Number: DP83867IR
Other Parts Discussed in Thread: TIDA-00204

Datasheet for DP83867IR states max input (Vpp) is 1.9V.

However TIDA-00204(https://www.ti.com/tool/TIDA-00204) Shows the device being driven by 3.3V clocks (see below excerpts from schematic).  Can you confirm if this is an error in the reference design, and this should be a 1.8V clock.

    Hello Matt leacock, 

    Thank you for the query.

    Thank you for brining this to our notice. We have been looking at making the updates for the clock.

    I do not have a timeline to update but if you are considering using TIDA-00204 be sure to change oscillator range to 1.8V.
