TEF6621
Tuner on main-board IC
Rev. 01.04 — 7 August 2008
Objective data sheet
1. General description
The TEF6621 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.
2. Features
I FM tuner for Japan, Europe and US reception
I AM tuner for Long Wave (LW) and Medium Wave (MW) reception
I Integrated AM Radio Frequency (RF) selectivity
I Integrated PLL tuning system; controlled via I2C-bus
I Fully integrated Local Oscillator (LO)
I No alignment needed
I Very easy application on the main board
I No critical RF components
I Fully integrated Intermediate Frequency (IF) filters and FM stereo decoder
I Fully integrated FM noise blanker
I Field strength (LEVEL), multipath [Wideband AM (WAM)] and noise [UltraSonic Noise
(USN)] dependent stereo blend
I Field strength (LEVEL), multipath (WAM) and noise (USN) dependent High-Cut
Control (HCC)
I Field strength (LEVEL), multipath (WAM) and noise (USN) dependent soft mute
I Single power supply

[1] SDA and SCL HIGH and LOW internal thresholds are specified according to an I2C-bus voltage of 2.5 V ± 10 % or 3.3 V ± 5 %. The
I2C-bus interface tolerates also SDA and SCL signals from a 5 V I2C-bus, but does not fulfill the 5 V I2C-bus specification completely.
The TEF6621 complies with the fast-mode I2C-bus protocol. The maximum I2C-bus communication speed is 400 kbit/s.

VCC = 8.5 V; Tamb = 25 °C; unless otherwise specified.
FM condition: all RF voltages refer to an unterminated RMS voltage with a source impedance 75 ; fmod = 1 kHz,
f = 22.5 kHz, de-emphasis = 50 µs, fRF = 97.1 MHz; unless otherwise specified.
AM condition: all RF voltages are RMS values measured at the input of a 15 pF/60 pF dummy aerial; fmod = 400 Hz,
m = 30 %, fRF = 990 kHz; unless otherwise specified.
All values measured in a test circuit according to Figure 29; default settings; audio signals measured at LOUT and ROUT with
IEC tuner filter (200 Hz to 15 kHz; IEC 60315-4); unless otherwise specified.
