Overview
The LA1837 is a single-chip AM/FM IF and MPX IC that
supports electronic tuning and was developed for use in
home stereo systems. It is optimal for use in automatic
station selection systems that use the SD and IF counting
techniques.
Functions
AM:
RF amplifier, mixer, oscillator, IF amplifier,
detector AGC, oscillator buffer, S-meter, narrow-
band SD, IF buffer
FM IF: IF amplifier, quadrature detector, S-meter, S-
curve detector, IF buffer output
MPX:
PLL stereo decoder, stereo display, forced mono,
VCO stop, post amplifier, audio muting, adjacent
channel interference rejection function
Features
On-chip MPX VCO (no external components required)
Adjacent channel interference rejection function
(third and fifth order)
Supports both the SD and the IF counting techniques.
The AM and FM SD sensitivities can be set independently.
The AM and FM output levels can be set independently.
Improved AM practical sensitivity and high-input
distortion characteristics
