General description D The TEF6621 is an AM/FM radio including Phase-Locked Loop (PLL) tuning system.
The system is designed in such a way, that it can be used as a world-wide tuner covering common FM and AM bands for radio reception.
All functions are controlled by the I2C-bus.
Besides the basic feature set it provides a good weak signal processing function.
