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
