Dual stage IF amplifier for cable tuners

Zarlink Semiconductor Inc 

SL2009

Dual stage IF amplifier for cable tuners

Features

• Single chip solution for tuner IF gain and AGC

• Contains 34 dB of AGC shared between two

AGC stages

• Design optimised for high signal handling with

low inter-modulation spurious generation

• I/O ports optimised to interface with standard

SAW filters

• ESD protection (Normal ESD handling

procedures should be observed)

Ordering Information

SL2009/KG/NP1T (Tape and Reel)

SL2009/KG/NP1S (Tubes)

The devices includes two stages of IF gain which are

both optimised to interface with inter-stage filters.

Both stages contain independent AGC facility, and

the first stage contains a level detect for control of the

tuner AGC.

Applications

• Cable Network interface modules and tuners

• Data communications systems

Description

The SL2009 is a dual IF amplifier intended for

application in cable tuners, and integrates all of the

IF gain and AGC required to deliver 1Vp-p in a

standard tuner configuration.
