Overview
The LA1787M 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
Features
Improved noise reduction methods
— The FM front end provides excellent 3-signal
characteristics equivalent to those of the LA1193M.
— Superlative listenability due to improved medium and
weak field noise canceller characteristics.
— Improved separation characteristics
— Anti-birdie filter
— Improved AM and FM thermal characteristics
— Excellent FM signal meter linearity
— Modified N.C. circuit for improved noise rejection

characteristics (
40 kHz)
Double conversion AM tuner (up conversion)
Reduces the number of external components required as
compared to earlier double conversion tuners, in
particular, no crystal is required (when used in
conjunction with the LC72144).
Sample-to-sample variation reduction circuit built into
the FM IF circuit.
(Fixed resistors are used for the SD, keyed AGC, mute
on adjustment, ATT, SNC, and HCC functions.)
Improved FM separation temperature characteristics
The LA1787 inherits the block arrangement of the
LA1780M and supports pin-compatible designs.
