Usage Notes
1. Notes on V
CC
and Ground
*
: 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
