DESCRIPTION

This TS636 is particularly intended for applications such as preamplification in telecommunication systems using multiple carriers. It has been minly designed to fit with ADSL chip-sets such as ASCOT ADSL chip-set for CPE.

The TS636 is a differential digitally controled variable gain amplifier featuring a high slew rate of 90V/µs, a large bandwidth, a very low distortion and a very low current and voltage noise.

The gain can be set from -9dB to +30dB through a 4bit digital word, with 3dB steps.
