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.
