Replace RTL8100 W/ RTL8110?

Has anyone tried pulling a RealTek RTL8100 (10/100 enet) and replacing it with a RTL8110 (gigabit enet)? According to RealTek's info page on the RTL8100, it is pin compatible (see first item under features) with the RTL8110S-32:

However, there is pin compatible, and then there is pin compatible. Sometimes it means, just drop it in and it works, and other times it means, bias these six pins differently and BTW, those four pins that were NC are now signals.

If RealTek made their datasheets available, I'd try to figure it out, but they don't.

So, anyone have any experience, thoughts, insight, or idle comments?

Thank you,

Jeff Walther

You'll get exactly that. Gb uses all 4 pairs of the cable but 10/100 uses only 2 pairs. Pin compatible probalby means the PCI side is the same.

Plus you will need a different or extra isolation transformer and board space for it.
