TEF6624
Tuner with high integration and high efficiency for radio
Rev. 01.05 — 9 June 2009
Objective data sheet
1. General description
The TEF6624 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.
The TEF6624 has been qualified for aftermarket car radios with reduced temperature
range of Tamb = 20 °C to +85 °C and not according to automotive standards. This
product is not designed for automotive Original Equipment Manufacturer (OEM) business.
2. Features
I Backwards compatible with TEF6621; equal footprint, application and performance
I Fully integrated RDS/RBDS demodulator with improved performance
I RDS demodulator data output via I2C-bus; 32-bit buffer for reduced read out
I RDS data available signalled by I2C-bus bit (polling)
I FM tuner for Japan, Europe, US and OIRT 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 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 Frequency (IF) filters and FM stereo decoder
I Fully integrated FM 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
