Overview
The LA1835 is an AM, FM IF and MPX single-chip tuner
IC that supports electronic tuning. It was developed
specifically for use in home stereo products and is optimal
for products with auto-seek systems, since it combines SD
and IF counting in its auto-seek implementation.
Furthermore, since the FM detector and MPX VCO
circuits are adjustment free, adoption of the LA1835 can
reduce the number of adjustment steps in the production
line.
Functions
AM:
RF amplifier, mixer, oscillator (with ALC), IF
amplifier, detector, AGC, oscillator buffer,
tuning indicator (narrow-band SD), IF buffer
output, stereo IF output
FM IF: IF amplifier, quadrature detector, band muting,
tuning indicator, IF buffer output, S-meter
MPX:
PLL stereo decoder, stereo indicator, forced
mono, VCO stop function, adjacent channel
interference rejection function (114 kHz), post-
amplifier with muting function
Features
Significant reduction in the number of manufacturing
adjustment steps
FM detector: Adjustment free (using a ceramic
discriminator)
MPX VCO: Adjustment free (using a ceramic
resonator)
Tuning indicator output provided. (This pin can also be
used as a narrow band stop signal and as a muting drive
output.)
Adjustable FM stop sensitivity and bandwidth
Built-in AM local oscillator buffer
Support for AM low band cut control
Adjustable AM stop sensitivity
