Fwiw, SalSB's Barlage this am recommended getting out of NN and into INTC and TXN. And Larry mentioned that he heard TXN mixed signal was working on a high speed ADSL single chip solution. The following would seem to imply otherwise: "...While ADSL systems are primarily digital, Mr. Teeple noted that copper phone lines still require signals to be transmitted in low-frequency analog format. "Copper wire was never made to transmita high-frequency) digital signal. It just wouldn't go very far." And that could spell a boom for the analog companies, since many of the firms developing ADSL chipsets are focusing on the DSPs, and opting to purchase analog technology. One exception to this is Texas Instruments, which has announced its own ADSL chipset, featuring two analog components. Unlike Burr-Brown, TI has split the AFE into a codec and a line driver, and is making the line-driver available on the open market. "Mixed signal is harder than the digital parts," noted Daniel Davis, worldwide multimedia marketing manager at TI. "This is not something you can just pick out of a library." TI's line driver features two op amps for drivers and two more for receivers, and the company says it can be used for ADSL systems, as well as other communication applications. "This is for anybody who wants multiple op amps," said Jim Quarfoot, a senior technical staff member at TI. "This dual line driver/receiver can be used in high-speed data communication systems and in applications like ADSL which are being developed to effectively get the most out of our installed infrastructure of copper telephone lines.".."
