TEA6849H
TYPE NUMBER
FM mixer 1 for conversion of FM RF (65 to 108 MHz
and US weather band) to IF of 10.7 MHz; the mixer
provides inherent image rejection; for European and
US FM band/WB (weather band) the mixer is driven with
a ‘high’ injection Local Oscillator (LO); in Japan
FM band and East Europe FM band the mixer is driven
with a ‘low’ injection LO
AM mixer 1 for conversion of AM RF to AM IF1 of
10.7 MHz
LC tuner oscillator providing mixer frequencies for
FM mixer and AM mixer 1
AM mixer 2 for conversion of AM IF1 to AM IF2 of
450 kHz
Crystal oscillator providing mixer frequencies for
AM mixer 2 and FM mixer 2 and reference for
synthesizer PLL, IF count, timing for Radio Data System
(RDS) update and reference frequency for car audio
signal processor ICs
Fast synthesizer PLL tuning system with local control for
inaudible RDS updating
Timing function for RDS update algorithm and control
signal output for car audio signal processor ICs
(TEA688x, SAA77xx, TEF689x)
I
Digital alignment circuit for bus controlled matching of
oscillator tuning voltage to FM antenna tank circuit
tuning voltage
AGC PIN diode drive circuit for FM RF AGC; AGC
detection at FM mixer input; the AGC PIN diode drive
can be activated by the I
search tuning; AGC threshold is a programmable and
keyed function switchable via the I
FM IF linear amplifier with high dynamic input range
FM mixer 2 for conversion of FM IF1 to FM IF2 of
450 kHz with inherent image rejection
Fully integrated dynamic selectivity and
FM demodulator at IF2; improved sensitivity with
dynamic threshold extension; centre frequency of IF2
selectivity alignment via the I

The TEA6849H is a single IC with car radio tuner for AM,
FM and Weather Band (WB) intended for microcontroller
tuning with the I
DESCRIPTION
Level detector for AM and FM with temperature
compensated output voltage; starting point and slope of
level output is programmable via the I
AM cascode AGC stage and RF PIN diode drive circuit;
AGC threshold detection at AM mixer 1 and IF2 AGC
input; threshold for detection at mixer 1 input is
programmable via the I
AM IF2 AGC and demodulator
AM AF output switchable to provide AM IF2 for
AM stereo decoder
AM noise blanker with detection at IF1 and blanking at
AM IF2
Software controlled flag output
Buffer output for weather band flag
Adjacent channel detector and modulation detector for
instantaneous bandwidth control of the integrated filter
Flag and voltage output indicating the actual bandwidth.
AM double conversion receiver for LW, MW and SW
(31 m, 41 m and 49 m bands) with IF1 = 10.7 MHz and
IF2 = 450 kHz
FM double conversion receiver with integrated image
rejection for IF1 and for IF2 capable of selecting US FM,
US weather, Europe FM, East Europe FM and
Japan FM bands; fully integrated dynamic selectivity at
450 kHz FM IF2; FM demodulator with dynamic
threshold extension; centre frequency alignment of IF2
selectivity via the I
The tuning system includes VCO, crystal oscillator and
PLL synthesizer on one chip.
