TEF6614

TEF6614 Advanced tuner on main-board IC Rev. 3 — 11 October 2011 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 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 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.
