I would recommend against that. Not unless you are trying to create a

I was worried about that, since other PHY data sheets list high-ish numbers

It's flux, but thanks for the heads-up! I went over everything with

Quite a piece of work. I hope you can continue to plug away at it.
I get that bit about mistakes. Even my simple PIC-based Documation card
reader interface board had a mistake (fortunately, one I could easily
fix without having to create a new board). Fortunately, my Mark-8
boards ended up mist
