DIFFERENTIAL VARIABLE GAIN AMPLIFIER
FOR ADSL LINE INTERFACE
s LOW NOISE : 4.7nV/√Hz
s LOW DISTORTION
s HIGH SLEW RATE : 90V/µs
s WIDE BANDWIDTH : 52MHz @ -3dB &
s GAIN PROGRAMMABLE from -9dB to +30dB
with 3dB STEPS
s POWER DOWN FUNCTION
This TS636 is particularly intended for applica-
tions such as preamplification in telecommunica-
tion 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 vari-
able 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.
The gain monotonicity is guaranteed by design.
The TS636 comes in SO-14 plastic packages.
s Preamplifier with automatic gain control for
Asymmetric Digital Subscriber Line (ADSL).
