The CA3189E from Harris Semiconductor is a monolithic integrated circuit that provides all the necessary functions for a comprehensive FM-IF system. It is designed for high-fidelity operation and is suitable for applications in high-fidelity, automotive, and communications receivers.
The device integrates a three-stage FM-IF amplifier/limiter configuration with level detectors, a doubly-balanced quadrature FM detector, and an audio amplifier. It also includes optional muting (squelch) circuitry. Key electrical characteristics include a maximum DC supply voltage of 16V and a maximum DC current output of 2mA. The typical distortion is rated at -0.1% with a double-tuned coil.
This IC is housed in a DIP package, suitable for through-hole mounting. Its operating temperature range is from -40°C to +85°C. The CA3189E offers features such as single-coil tuning capability, improved signal-to-noise ratio, and externally programmable recovered audio level and on-channel step for search control.
Distortion in a CA3189E FM-IF system is primarily influenced by the phase linearity of the outboard detector coil. The device also provides programmable AGC voltage for the RF amplifier and internal supply voltage regulators.
