Figure 2 - Block diagram
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)
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.
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.
