TDA7088T FM receiver circuit

TDA7088T FM receiver circuit for battery supply
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 1.8 V. Mechanical tuning, this is possible with or without integrating AFC circuit, Electrical tuning; this is realized by one directional (band-up) search tuning facility, including RESET to the lower-band limit.
The TDA7088T 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 70 kHz. Selectivity is achieved by active RC-filters. De-tuning related to the IF and too weak input signals is suppressed by the mute circuit.
