The CD9088CB, CD9088 is a single-chip electronically tuned FM radio circuit. Its peripheral circuit is simple and low in cost. The circuit has a built-in phase-locked loop system with a frequency of 70kHz. It is selectively realized by an active RC filter. The mute circuit can suppress non-IF signals and too weak IF signals. Its characteristics are as follows.


1. Contains all functional circuits of a mono radio from RF input to audio output

2. Mute circuit

3. Built-in automatic frequency control system can be used for mechanical tuning

4. Power polarity protection

5. Operating supply voltage can be as low as 1.8V

6. Automatic search can be realized in the frequency range from 88MHz key reset to 108 MHz
