Product data sheet
1. General description
The TEF6614 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 mon 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 and a dynamic bandwidth control at FM reception.
It includes a newly developed demodulator for data reception of Radio Data System (RDS) and Radio Broadcast Data System (RBDS) transmissions.
2. Features and benefits
