LM3089 FM Receiver IF System
General Description
The LM3089 has been designed to provide all the major
functions required for modern FM IF designs of automotive,
high-fidelity and communications receivers.
Features
Y
Three stage IF amplifier/limiter provides 12
m
V (typ)
b
3 dB limiting sensitivity
Y
Balanced product detector and audio amplifier provide
400 mV (typ) of recovered audio with distortion as low
as 0.1% with proper external coil designs.
Y
Four internal carrier level detectors provide delayed
AGC signal to tuner, IF level meter drive current and in-
terchannel mute control
Y
AFC amplifier provides AFC current for tuner and/or
center tuning meters
Y
Improved operating and temperature performance, es-
pecially when using high Q quadrature coils in narrow
band FM communications receivers
Y
No mute circuit latchup problems
Y
A direct replacement for CA3089E
