SINGLE-CHIP TUNER IC FOR CAR RADIOS
SA1787
DESCRIPTION
The SA1787 is a high performance tuner circuit for AM and FM car
radio. It integrates mixer, IF amplifier, signal detection circuit and
stereo decoder for AM and FM. It achieves stereo tuning with
advanced technology and less peripheral components.
FEATURES
FM-Part
