Silan Semiconductors FM RECEIVER CIRCUIT FOR BATTERY SUPPLY DESCRIPTION The SA1088 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.
SA1088 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...
