D7088 Datasheet | Shaoxing Silicore

DESCRIPTION The D7088 is a bipolar integrated circuit for use in mono portable and pocket radios. It is used when a mi nimu m of peripheral co mponents (of small dimensions and low costs) is important. The circuit contains a frequency-locked-loop (FLL) sys te m with an Interme d iate Frequency (IF) of about 70k Hz. Selectivity is achieved by activ e RC-filters. De-tuning related to the IF and too weak inpu t sign als is suppressed by the mute circuit. FEATURES z z z z z z z z z z Equipped with all stages of a mo n o receiver fro m antenna to au dio output Mute circuit Search tuning with a single varicap diode Mechan ical tuning with Integrating AFC AM application supported Power supply polarity protection Power supply voltage down to 1.8V. Package: SOP16 Mechan ical tuning; this is possible with or without integrating AFC circuit Electrical tuning; th is is realized by one directional (band-up) search tuning facility, including RESET to th e lower-band li mit.
