TS636I Datasheet - STMicroelectronics

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.

■ LOW NOISE : 4.7nV/√Hz

■ WIDE BANDWIDTH : 52MHz @ -3dB & 18dB gain
■ GAIN PROGRAMMABLE from -9dB to +30dB with 3dB STEPS
■ POWER DOWN FUNCTION

APPLICATION
■ Preamplifier with automatic gain control for Asymmetric Digital Subscriber Line (ADSL).
