GENERAL DESCRIPTION

The D7088 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.

Package: SOP16

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.
