1. General description

The TEF6901A is a single-chip car radio integrated circuit with FM/AM tuner, stereo

decoder, weak signal processing and audio processing. Radio Data System (RDS)/Radio

Broadcast Data System (RBDS) demodulator for radio data reception is included.

FM tuner with double conversion to IF1 = 10.7 MHz and IF2 = 450 kHz with integrated

image rejection for both IF1 and IF2; integrated channel ﬁlter with variable bandwidth

control; capable of US FM, Europe FM, Japan FM and Eastern Europe FM. AM tuner with

double conversion to IF1 = 10.7 MHz and IF2 = 450 kHz; capable of Long Wave (LW),

Medium Wave (MW) and full range Short Wave (SW) (11 m to 120 m bands).

Multiplex (MPX) stereo decoder, ignition noise blanker and extensive weak signal

processing.

Audio processing with ﬂexible source selection, volume, balance, fader, input gain control

and inaudible tuning mute. Integrated audio ﬁlters for bass and treble and loudness control

function.

The device can be controlled via the fast-mode I

C-bus (400 kHz) and includes

autonomous tuning functions for easy control without microcontroller timing. No manual

alignments are required.
