SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Ordering number : ENN8085
40706 MS OT B8-7756 No.8085-1/41
Overview
The LA1776M integrates all six blocks required in a car radio tuner on a single chip.
Functions
FM front end
FM IF
Noise canceller
Multiplex
AM up-conversion
FM/AM switch
MRC
Feature
Reduced noise in the mixer and amplifier blocks for improved performance
Increased FM front end mixer dynamic range for improved three signal characteristics
Improved AM practical sensitivity and saturated signal-to-noise ratio
S-meter sample-to-sample variations can be improved by using the FM S-meter shift function (Fixed resistors can
be used for the SD, keyed AGC, muting on adjustment, muting attenuation, SNC, and HCC.)
High-speed searching can be implemented using the FM band mute time constant switching function.
Superb listenability provided by improved medium and weak field noise canceller characteristics.
Improved separation temperature dependency characteristics
Excellent FM S-meter voltage linearity
Noise rejection improved by modifications to the NC circuit
Sample-to-sample variation correction circuit (zapping) in the FM IF circuit
Stopping at stations with heavy interference is prevented by increasing the AM wide AGC sensitivity by 10 dB
during seek operations
Built-in anti-birdie filter
