Pin 61
* Pin 6
Pin 3
V CC for the FM IF, AM, NC, MPX, and MRC blocks
Ground for the FM IF and AM blocks
Ground for the NC, MPX, and MRC blocks
V CC for the FM front end, AM first mixer, and first oscillator blocks
V CC for the FM front end and AGC blocks, and the AM/FM switching pin
Ground for the FM front end, first mixer, and first oscillator blocks
* : When applying the V CC voltage to pin 6, that voltage must not exceed the pin 40 and pin 61 V CC voltages.
(This condition must be checked carefully when first applying the pin 6 voltage.)
2. Notes on AM Coil Connection
The V CC used for the first oscillator coil connected to pin 7 must be at the same potential as pin 61.
Connect to the IFT connected with pin 45, and to the MIX coil connected with pin 54. V CC must be at the same potential
as pin 40.
3. AM/FM Switching
Pin 6 is also used as the FM front end and RF AGC V CC

LA1787M Overview
1. Notes on the LA1781M, LA1784M, and LA1787M
The LA1784M is a version of the LA1781M that uses an external oscillator circuit, and has the same characteristics as
the LA1781M.
The LA1787M is a version of the LA1784M that features improved characteristics.
LA1781M
LA1784M
This product is a version of the LA1781M
with the oscillator circuit removed. It
supports the use of an external oscillator
LA1787M
The LA1787M features improved
characteristics over the LA1781M
and LA1784M.
circuit.
It has the same characteristics as the
LA1781M.
