Fm If System

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 amplier/limiter conguration with level detectors for each stage, a doubly-balanced quadrature FM detector and an Audio amplier 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-delity 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. By Intersil Corporation
