TEF6621

Product Summary

The TEF6621 is an AM/FM radio including Phase-Locked Loop (PLL) tuning system. The system is designed in such a way, that the TEF6621 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.
