Description :

a single-chip electrically tuned FM radio circuit. Its peripheral circuit is simple. The application cost is low. The built-in PLL system with 70kHz IF frequency is selectively implemented by active RC filter. The mute circuit can suppress non-IF signals and too weak IF signals.

1. All functional circuits containing radio from RF input to audio output
2. Silent circuit
3. Built-in automatic frequency control system for mechanical tuning
4. Power polarity protection
5. Working power supply voltage can be as low as 1.8V
6. Automatic search from 88MHz key reset to 108 MHz frequency range

Description :

CD9088CB is a monolithic power FM radio tuning circuit, the external circuit is simple, low-cost applications, phase-locked loop circuit built-in frequent rate of 70kHz Department. EC selectivity achieved by active RC filter, mute circuit inhibit non-IF signal and the IF signal is too weak. The IC is a bipolar integrated circuit for use in mono portable and pocket radios.


1. Equipped with all stages of a mono receiver from antenna to audio output
2 Mute circuit
3. Search tuning with a single varicap diode
4. Mechanical tuning with integrating AFC
5. AM application supported
6. Power supply polarity protection


CD9088CB pinout


1. Mechanical tuning; this is possible with or without integrating AFC circuit
2. Electrical tuning; this is realized by one directional (band-up) search tuning facility, including RESET to the lower-band limit
