FEATURES
1.1
General
I
2
C-bus compatible
Digital alignment/adjustment via I
2
C-bus:
– FM noise blanker sensitivity
– FM stereo noise canceller
– FM High Cut Control (HCC)
– FM stereo separation.
FM audio processing hold for RDS updating; holds the
detectors for the FM weak signal processing in their
present state
FM bandwidth limiting; limits the bandwidth of the FM
audio signal with external capacitors
AM stereo input; AM stereo audio can be fed in at the
pins for the de-emphasis capacitors; this will provide
8 dB of gain to the AM audio.
1.2
Stereo decoder and noise blanking
FM stereo decoder
Accepts FM multiplex signals and AM audio at input
Pilot detector and pilot canceller
De-emphasis selectable between 75 and 50
μ
s
AM noise blanker: impulse noise detector and an audio
hold.
1.3
Weak signal processing
FM weak signal processing: six signal condition
detectors, soft mute, stereo noise canceller (blend), and
high cut control (roll-off).
1.4
Audio pre-amplifier
Source selector for 6 sources: 2 stereo inputs external
(channels A and B), 1 symmetrical stereo input
(channel C), 1 symmetrical mono input (D), 1 internal
stereo input (AM or FM), and 1 chime/diagnostic mono
input
Volume 1 control from +20 to
56 dB in 1 dB steps;
programmable 20 dB loudness control included
Volume 2 control from 0 to
56 dB in 1 dB steps,
56,
58.5,
62,
68 dB and mute
Programmable loudness control with bass boost as well
as bass and treble boost
Treble control from
14 to +14 dB in 2 dB steps
Bass control from
18 to +18 dB in 2 dB steps with
selectable characteristic
Analog Step Interpolation (ASI) minimizes pops by
smoothing out the transitions in the audio signal when a
switch is made
Audio Blend Control (ABC) minimizes pops by
automatically incrementing the volume and loudness
controls through each step between their present
settings and the new settings
Rear Seat Audio (RSA) can select different sources for
the front and rear speakers
Chime input: can be sent to any audio output, at any
volume level
Chime adder circuit: chime input can also be summed
with left front and/or right front audio, or be turned off.

GENERAL DESCRIPTION
The TEA6886HL is a monolithic bipolar integrated circuit
providing the stereo decoder function and ignition noise
blanking facility combined with source selector and
tone/volume control for AM/FM car radio applications. The
device operates with a power supply voltage range from
7.8 to 9.2 V and a typical current consumption of 40 mA.
