Overview
The LA1143 is an IF system IC designed for FM car stereo
receivers. It features versatile muting characteristics and
allows receiver designers to realize the muting
performance according to their design concept. Since the
muting characteristics can be varied with a switch or a
semi-fixed resistor, DX-Local switching will be
accomplished with ease.
Functions
IF amplification/limiter
AF preamplifier
Signal meter output
Muting at detuning
Quadrature detector
AFC output
AGC output
Muting at small input

Features
1. Versatile mutings
a) When muting operation is performed under a weak signal strength, an attenuation slope of the audio output against
the input signal strength variations can be set at any given value.
b) Maximum muting attenuation can be selected to be approximately 6 to 40dB.
c) Input signal strength level which actuates the muting circuit can be set freely.
2. High limiting sensitivity (25 dBμ typ. with muting off) provides a good quieting characteristic.
3. High S/N (78dB typ.)
4. Low distortion (0.05% typ.) available, if used with double-tuned circuits.
5. Good AMR (63dB with 6 stages of differential IF amplifiers).
6. Signal meter drive output proportional to the input signal strength in dB (suitable to control multiplex IC LA3373).
7. Clamped (±V
BE
) AFC output, bandwidth adjustable.
8. Delayed AGC output for front end circuit.
