Monolithic Linear IC
For Home Stereo IC with Electronic Tuning Support
Single-Chip IC
LA1837
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.
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.
Functions
AM :
RF amplifier, mixer, oscillator, IF amplifier, detector AGC, oscillator buffer, S-meter, narrowband SD,
IF buffer
FM-IF :
IF amplifier, quadrature detector, S-meter, Scurve detector, IF buffer output
MPX :
PLL stereo decoder, stereo display, forced mono, VCO stop, post amplifier, audio muting, adjacent channel
interference rejection function
