Overview
The LA1838 is designed for use in home stereo systems
and is a single-chip tuner IC that provides electronic
tuning functions for AM, FM IF, and MPX reception. It is
optimal for use in products that adopt an automatic tuning
system based on an IF count.
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, SD
(signal detection), S-curve detection, IF buffer
output
MPX:
PLL stereo decoder, stereo display, forced
monaural, VCO stop, post amplifier, audio
muting, adjacent channel interference rejection
function
Features
Integrated MPX VCO (External components are no
longer required.)
Built-in adjacent channel interference rejection function
(third and fifth order)
Adjustment-free FM detector circuit (Uses a ceramic
discriminator.)
The AM and FM SD sensitivities can be set
independently.
The AM and FM output levels can be set independently.
Improved useable AM sensitivity and strong field
distortion characteristics.
