FM RECEIVER CIRCUIT FOR BATTERY SUPPLY
YD9088
DESCRIPTION
The YD9088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a
minimum of peripheral 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 signals is suppressed by the mute circuit.
FEATURES
*Equipped with all stages of a mono receiver form 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
