Description
The Harris CA3189E is a monolithic integrated circuit that
provides all the functions of a comprehensive FM-lF system.
The block diagram of the CA3189E includes a three-stage
FM-lF 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 programmable delayed AGC
for the RF tuner, an AFC drive circuit, and an output signal to
drive a tuning meter and/or provide stereo switching logic. In
addition, internal power-supply regulators maintain a nearly
constant current drain over the voltage supply range of
+8.5V to +16V.
The CA3189E is ideal for high-fidelity operation. Distortion in
a CA3189E FM-lF System is primarily a function of the
phase linearity characteristic of the outboard detector coil.
The CA3189E has all the features of the CA3089E plus addi-
tions. See CA3189E features compared to the CA3089E in
Table 1.
