Monolithic Linear IC
LA1776M Single-Chip Tuner IC for Car Radios
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
