Upon further research and reflection, my reference to a single chip "digital" solution out of ADI and TXN appears to have been incorrect.
I remembered reading that ADI won 3COM business (away from TXN) with a single TOTAL chip (ie., both analog AND DSP) 56K solution. At the time I (errantly) *presumed* this approach would be applied to ADSL, at least with the digital components. Larry Brew's post (the TXN post I url'd) reinforced this idea in me.
Whereas it certainly might, no announcements to this effect have been made. And from other research, I would doubt this is being pursued - at least not with DSP. As I understand, MOT has tried to get analog and ASIC on a single chip, and continues to struggle.
My GUESS is that the single-chip mixed signal approach that Larry mentioned, was NOT for ADSL was stated, but for the 56K business they lost from 3COM (their biggest buyer). I may be wrong, and I'll ask that he verify this (as I will also attempt to do). But the pieces didn't seem to fit quite right in my previous post, so I thought this follow-up appropriate (if uncertain).
Details of the Falcon that I posted are, however, correct to the best of my knowledge. It seem that PAIR may have the best (ie., most efficient in power, size, cost, yields, etc) ADSL solution available (*WHEN* it comes available <g>).
Another long day (how 'bout that SLOT and WCII?)
