TEF6601/V1
Tuner on main board IC
Rev. 0.1 — 25 August 2006
Objective specification
1. General description
The Tuner On Main board IC (TEF6601T/V1) is an AM/FM radio including PLL tuning
system. The system is designed in such a way, that it can be used as a world-wide tuner
covering the common FM and AM bands for radio reception. The device is controlled by
the I2C-bus. Besides the basic feature set it provides a good weak signal processing.
2. Features
FM tuner for Japan, Europe and US AM tuner for LW and MW reception
reception
AM RF tracking selectivity
Integrated PLL tuning system including
automatic low/high side LO injection (not
supported by /V1)
Fully Integrated local oscillator
No alignment needed
Very easy application on the mainboard No critical RF components
Fully integrated IF filters and FM stereo Fully integrated FM noise blanker

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- or low- side injection (not
supported by /V1).
7.4 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 with no alignment required.
7.5 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
of Soft mute, High Cut Control and mono-stereo blend are controlled accordingly to
maintain the best possible audio quality in case of poor signal conditions.
