Abstract :
A /spl plusmn/6V ADSL CO driver delivers 20.4dBm power into a 100/spl Omega/ load with 5.3 crest factor using internally pumped power supplies. In a 1:1.1 transformer reference design, 1E-08 BER is measured while driving 8.16Mb/s down a 6.5kft line. Data rates up to 8Mb/s are measured. The device uses a 26V SOI bipolar process with 744mW of total supply.
