TLK100 Ethernet PHY

Other Parts Discussed in Thread: TLK100, TLK110

Hello,

For an external clock source, please clarify if the TLK100 Ethernet PHY really needs a "nominal voltage of 1.8V" as stated in the datasheet (see page 36 of datasheet).

I believe it should be 3.3V nominal.

Also, a very similar part (TLK110) states "a nominal voltage of 3.3V" in that datasheet (see page 40), which would correspond to CMOS voltage levels I would expect in a single power supply design using either part.

This is a big design difference, so please advise ASAP. 

Thanks!
