FM receiver circuit for battery supply
Product specification
TDA7088T
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 1.8 V.
GENERAL DESCRIPTION
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.
APPLICATIONS
• 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.
