National Semiconducters is discontinouing production of it's LM1893/LM2893
Carrier-Current Transceiver IC's (see their website).
Look for PhilipsTDA5051(A) Home automation modem and SGS-Thomson ST7537
Power line modem chips (lots of appnotes and technical background articles
on SGS-Thomson's website).
I just don't have at hand the URL of the appropiate websites, but it will be
easy to find them with Hotbot or Yahoo.
