Some parameters are copied from chip vendor datasheets, mention which ones and where the data is coming from.

And explain that those are not significantly affected by PCB layout or other aspects of the card design. Those that are should not be in the datasheets.

3654502d.

Also removed capacitance & propagation specs from RJ45-TTL, the traces on the PCB should have a major impact.

I think the pulse width distortion & peak jitter specs in BNC/SMA-TTL are from the isolators. But the transceivers may contribute more distortion due to differences between propagation of L->H and H->L. (not sure about the peak jitter)
