FM RECEIVER CIRCUIT FOR BATTERY

SUPPLY

DESCRIPTION

The SC1088 is a bipolar integrated circuit for use in mono

portable and pocket radios. It is used when a minimum of perpheral

components (of small dimensions and low costs) is important. The

circuit contains a frequency-locked-loop(FLL) system with an

intermediate frequency(IF) of about 70kHz. Selectivity is achieved

by active RC-filters. De-tuning related to the IF and too weak input

signal is suppressed by the mute circuit.

FEATURES

* Equipped with all stages of a mono receiver from antenna to

audio output.

* Mute Circuit

* Search tuning with a single varicap diode

* Mechanical tuning with integrating AFC

* AM application supported

* Power supply polarity protection

* Power supply voltage down to 1.8V

SOP-16

APPLICATION

1. Mechanical tuning: This is possible with or without integrated AFC circuit

2. Electrical tuning: This is realized by one directional(band-up) search tuning facility, including RESET to the

lower-band limit.
