TEF6606
Advanced tuner on main-board IC
Rev. 01.03 — 12 June 2007
Objective data sheet
1. General description
The TEF6606 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.
2. Features
I FM tuner for Japan, Europe, US and OIRT reception
I AM tuner for Long Wave (LW), Medium Wave (MW) and Short Wave (SW) reception
I Integrated AM Radio Frequency (RF) selectivity
I Integrated PLL tuning system; controlled via I2C-bus including automatic low/high side
Local Oscillator (LO) injection
I Fully integrated LO
I No alignment needed
I Very easy application on the main board
I No critical RF components
I Fully integrated Intermediate Frequencywww.DataSheet.co.kr (IF) filters and FM stereo decoder
I Fully integrated FM noise blanker
I Fully integrated AM audio noise blanker
I Field strength (LEVEL), multipath [Wideband AM (WAM)], noise [UltraSonic Noise
(USN)] and deviation dependent stereo blend
I Field strength (LEVEL), multipath (WAM), noise (USN) and deviation dependent
High-Cut Control (HCC)
I Field strength (LEVEL), multipath (WAM) and noise (USN) dependent soft mute
I Adjacent channel and deviation dependent IF bandwidth control [Precision Adjacent
Channel Suppression (PACS)]
I Single power supply
I Qualified in accordance with AEC-Q100

7. Functional description
7.1 FM tuner
The RF input signal is mixed to a low IF with inherent image suppression. The IF signal is

filtered and demodulated. The complete signal path is fully integrated.
7.2 AM tuner
The RF signal is filtered and mixed to a low IF with inherent image suppression. The IF
signals are filtered and demodulated. The signal path is highly integrated.
7.3 PLL tuning system
The PLL tuning system includes a fully integrated VCO. To avoid problems with unwanted
signals on image side, the receiver controls automatically high-side or low-side injection.
7.4 Signal dependent FM IF bandwidth control
The bandwidth of the FM IF filter will be controlled by an adjacent channel detector and a
deviation detector to optimize the reception.
7.5 FM stereo decoder
The MPX signal from the FM tuner is translated by the stereo decoder into a left and right
audio channel. Good channel separation is achieved without alignment.
7.6 Weak signal processing and noise blanker
The reception quality of the station received is measured by a combination of detectors:
field strength (LEVEL), multipath (WAM) and noise (USN). The audio processing functions
soft mute, HCC and stereo blend are controlled accordingly to maintain the best possible
