- AMD makes a few chips that might just be what you're looking for.
- They're perhaps a bit faster than needed though.
- Look up the AM7968 and AM7969, a.k.a TAXIchips.
- The former accepts a parallel word which gets serialized and sent to
- the latter, which convert it back to parallel format. Bit rates up
- to 100M bits/s.
-
- Cost was around $35 per chip, when I last looked.
