If you have the logical signals, then it's no problem at all
to provide them at the appropriate voltage levels, if you
are doing an ASIC anyways. Just choose the library elements
for the pins/pads accordingly.

I doubt that many people would like to do that. If possible,
then TRV10 should provide as many electrical standards as
possible, because each additional chip means additional cost.
(more just then the price of the chip.. a lot more)
And people like to avoid that.

Actualy, that's a nice idea. The problem with this is, taht it
would require an additonal connector on the board which is specified
for high frequency signals. Those connectors tend to be very expensive
unless you use one that is an industry standard (maybe scsi?).
But even then, it will increase the card cost and thus make its
position on the market more difficult.
