CA3089
FN0561.4
FM IF System
Description
Intersil CA3089 is a monolithic integrated circuit that pro-
vides all the functions of a comprehensive FM-IF system.
The block diagram shows the CA3089 features, which
include a three-stage FM-IF amplifier/limiter configuration
with level detectors for each stage, a doubly-balanced
quadrature FM detector and an audio amplifier that features
the optional use of a muting (squelch) circuit.
The advanced circuit design of the IF system includes desir-
able deluxe features such as delayed AGC for the RF tuner,
and AFC drive circuit, and an output signal to drive a tuning
meter and/or provide stereo switching logic. In addition, inter-
nal power supply regulators maintain a nearly constant cur-
rent drain over the voltage supply range of +8.5V to +16V.
The CA3089 is ideal for high-fidelity operation. Distortion in a
CA3089 FM-IF System is primarily a function of the phase
linearity characteristic of the outboard detector coil.
