QW-R110-016,A

FM RECEIVER CIRCUIT FOR

BATTERY SUPPLY

DESCRIPTION

The UTC TDA7088 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 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

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.
