Thanks Eugene, though I’ll need the actual input capacitance as I’m driving multiple ICs with a single oscillator.

Oscillator or generator? Crystal oscillator will require both XI and XO, and I doubt you can connect an oscillator to two chips (it will require buffering at least). If you talk about generator (buffered oscillator), then you can take approx 10 pF for W5500 internal capacitance.

Yes, oscillator (CB3LV-3C-25M0000) not crystal.
10pF sounds high, i didn’t work with ICs that have more than 5pF capacitance on their clock input pin. Is there an actual electrical characteristics table? Someone/somewhere must posses this kind of information…
thanks anyways
