Interesting question! I am trying to get my hands on a +/- 2% and a +/- 4% at 25 MHz to try it out! Ethernet has got to be tolerant of variations in clock, and the PLL for the clock extractor has to work pretty fast, so I have a feeling that it will work! I plan to try it as soon as I can get some parts.

What about the 25 MHz PHY oscillator? Will this work there (dithering ethernet waveforms by 2%), and is a 25 MHz version available? I'd imagine that the PHY oscillator is nearly as important as the C400 oscillator in total radiated emissions. We're looking at adding this/these to TStik since a lot of customers seem to be concerned with radiated EMI.
