Overview
The LA1824 is a single-chip tuner IC that incorporates
FM/AM and MPX circuits.
The built-in MPX-VCO allows this IC to be adjustment free
and to require no external components.
Features
FM, AM and MPX integrated in a single-chip.
Adjustment free MPX-VCO
: No ceramic resonator used.
FM front-end : Local OSC voltage reduced.
FM stereo and FM/AM tuning indicator
output provided.
Package : DIP-24S.
Functions
FM
: RF amplifier, mixer, oscillator, IF amplifier,
detector, signal meter, tuning indicator.
AM
: RF amplifier, mixer, oscillator (with ALC),
IF amplifier, detector, AGC, tuning indicator.
MPX : PLL stereo decoder, stereo indicator, VCO on chip, forced monaural.
