1.1 General

• I2C-bus compatible

• Digital alignment/adjustment via I2C-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 signal and AM audio at input

• Pilot detector and pilot canceller

• De-emphasis selectable between 75 and 50 µs

Processor (CASP)

7 FUNCTIONAL DESCRIPTION

7.1 Stereo decoder

The MPX input is the null-node of an operational amplifier
with internal feedback resistor. Adapting the stereo
decoder input to the level of the MPX signal, coming from
the FM demodulator output, is realized by the value of the
input series resistor RIN. To this input a second source
(AM detector output) can be fed by current addition.

The input amplifier is followed by an integrated 4th-order
Bessel low-pass filter with a cut-off frequency of 80 kHz.
It provides the necessary signal delay for FM noise
blanking and damping of high frequency interference at
the stereo decoder input.

The output signal of this filter is fed to the soft mute control
circuitry, the output is voltage-to-current converted and
then fed to the phase detector, pilot detector and pilot
canceller circuits, contained in the stereo decoder PLL
block. A PLL is used for regeneration of the 38 kHz
subcarrier. The fully integrated oscillator is adjusted by
means of a digital auxiliary PLL into the capture range of
the main PLL. The auxiliary PLL needs an external
reference frequency (75.4 kHz) which is provided by the
TEA6840H. The required 19 and 38 kHz signals are
generated by division of the oscillator output signal in a
logic circuit. The 19 kHz quadrature phase signal is fed to
the 19 kHz phase detector, where it is compared with the
incoming pilot tone. The DC output signal of the phase
detector controls the oscillator (PLL).

The pilot present detector is driven by an internally
generated in-phase 19 kHz signal. Its pilot dependent DC
output voltage is fed to a threshold switch, which activates
the pilot indicator bit and switches the stereo decoder to
stereo operation. The same DC voltage is used to control
theamplitudeofananti-phaseinternallygenerated 19 kHz
signal. The pilot tone is compensated by this anti-phase
19 kHz signal in the pilot canceller.

The pilot cancelled signal is fed to the matrix. There, the
side signal is demodulated and combined with the main
signal to the left and right audio channels. Compensation
for roll-off in the incoming MPX signal caused by the IF
filters and the FM demodulator is typically realized by an
external compensation network at pin MPXIN, individual
alignment is achieved by I2C-bus controlled amplification
of the side signal (DAA). A smooth mono-to-stereo
takeover is achieved by controlling the efficiency of the
matrix with the help of the SNC peak detector.

The matrix is followed by the FM noise suppression gates,
which are combined with FM single poles and High Cut
Control (HCC).

TEA6886HL

Thesinglepoleisdefinedbyinternal resistors and external
capacitors. Audio is fed from the gate circuits to the
switchable de-emphasis, where the demodulated AM
stereo signal can be fed in. After de-emphasis the signal
passes to the output buffers and is fed to the radio input of
the source selector. For HCC, the time constant of the
single pole contained in the output buffer can be changed
to higher values. This function is controlled by an average
detector contained in the multipath and fading detector.

7.2 FM noise blanker

The input of the ignition noise blanker is coupled to the
MPXRDS input signal and to the LEVEL input. Both
signalsarefedviaseparate120 kHz filters and rectifiers to
anaddercircuit.Theoutputsignalof the adder circuit is fed
in parallel to the noise detector and the interference
detector. The noise detector is a negative peak detector.
Its output controls the trigger sensitivity (prevention of
false triggering at noisy input signals) and the gain of the
MPX high-pass filter. The output of the interference
detector, when receiving a steep pulse, fires a single-shot
trigger circuit, contained in the pulse former circuitry. The
time constant of the single-shot trigger circuit is defined by
an internal capacitor, and its output activates the blanking
gates in the audio.

7.3 AM noise blanker

The AM noise blanking pulse is derived from the AM audio
signal which is fed into pin AMNBIN with the help of a
peak-to-averagecomparator. The blanking time is set by a
pulse former with external capacitor. The blanking pulse is
fed to the gate in the AM audio path and out at
pin AMHOLD to operate the gate built into the external
AM stereo processor.

7.4 Multipath/fading detection and weak signal
control

For FM signal quality dependent controls there is a built-in
combination of six detectors. These detectors are driven
by the level information direct, by the AC components on
thelevelviaa20 kHz band-pass filter (AM wideband) or by
the high notes present at the FM demodulator output via a
60 kHz high-pass filter (ultrasonic noise). The relationship
between the DC level and the AC components is
programmable by the I2C-bus (2 bits each). The output of
the level buffer, AM wideband detector and ultrasonic
noise detector are analog-to-digital converted and
readable by the I2C-bus.

2003 Feb 04 10

Philips Semiconductors Product specification

Up-level Car radio Analog Signal
Processor (CASP)

For the period of fast RDS updating soft mute, SNC and
HCC can be put on hold. The AM wideband peak detector
and the ultrasonic noise peak detector are reset by a
switch signal delivered from the TEA6840H via pin
FMHOLD.

The six separate detecting circuits are as follows:

1. The AM wideband noise peak detector is driven from
a 20 kHz band-pass filter connected to the level buffer
output. The time constant is defined by an external
capacitor connected to pin TWBAM2. The output
voltage of the detector is analog-to-digital converted
by a 3-bit ADC.

2. The AM wideband noise average detector is driven
from a 20 kHz band-pass filter connected to the level
buffer output. The time constant is defined by an
external capacitor connected to pin TWBAM1. The
outputofthe detector is connected to the Stereo Noise
Control (SNC) circuit.

3. The ultrasonic noise peak detector is driven from a
60 kHz high-pass filter connected to the MPX signal
from pin MPXRDS. The time constant is defined by an
external capacitor connected to pin TUSN2. The
output voltage of the detector is analog-to-digital
converted by a 3-bit ADC.

4. The ultrasonic noise average detector is driven from a
60 kHz high-pass filter connected to the MPX signal
from pin MPXRDS. The time constant is defined by an
external capacitor connected to pin TUSN1. The
output of the detector is connected to soft mute control
and stereo noise control circuits.

5. For soft mute and high cut control purposes an
average detector with an externally defined time
constant (TMUTE) is provided. The detector is driven
byleveloutputonly.Softmuteandhighcutcontrolcan

6. The stereo noise control peak detector with an
externally defined time constant (TSNC) is driven by
DC level output, AM wideband and ultrasonic noise
outputs.Itprovidesthestereo blend facility (SNC).The
starting point and slope of the stereo blend can be
chosen via the I2C-bus controlled reference voltage.

7.5 Tone/volume control

The tone/volume control part consists of the following
functions:

• Source selector

• Loudness

• Volume 1

• Treble

• Bass

• Volume 2

• Rear Seat Audio (RSA) selector

• Chime adder

• Analog step interpolation

• Audio blend control.

The stages loudness, volume 1, bass and volume 2
include the Analog Step Interpolation (ASI) function. This
minimizes pops by smoothing out the transitions in the
audio signal during switching. The transition time is
I2C-bus programmable in a range of 1 : 24 in four steps.

The stages loudness, volume 1 and volume 2 also have
the Audio Blend Control (ABC) function. This minimizes
pops by automatically incrementing the volume and
loudnesscontrolsthrougheach step between theirpresent
settings and the new settings. The speed of the ABC
function is correlated with the transition time of the ASI
function.

All stages are controlled via the I2C-bus.

7.5.1 SOURCE SELECTOR

The source selector allows the selection between
6 sources:

• 2 external stereo inputs (ALI, ARI, BLI and BRI)

• 1 external symmetrical stereo input (CLIP, CRIP and

CCOM)

• 1 external symmetrical mono input (MONOP and

MONON)

• 1 internal stereo input (AM/FM)

• 1 chime/diagnostic mono input (CHIME).

A chime input signal can be sent to any audio output, at
any volume level, via the chime/diagnostic mono input.

7.5.2 LOUDNESS

The output of the source selector is fed into the loudness
circuitviatheexternalcapacitorC
and LOPI) and C
Depending on the external circuits for the left and the right
channel, only a bass boost or bass and treble boost is
available.Theexternalcircuits illustrated in Figs 13and 15
will produce the curves illustrated in Figs 14 and 16

7.5.5 BASS
Thebasscontrolisthenext stage. The characteristic ofthe

bass curves depends upon the external circuits connected
to pins LBO and LBI (left channel) and pins RBO and RBI
(rightchannel)andalsouponthe setting of bit BSYM(MSB
of the bass control byte). When BSYM = 1, an equalizer
characteristic is obtained and when BSYM = 0, a shelving
characteristic is obtained.

Figures 17 and 18 show the bass curves with an external
circuit of 2 × 220 nF capacitors and a resistor of 3.3 kΩ for
each channel with different values for BSYM. Figure 19
shows the bass curves with an external capacitor of 47 nF
for each channel and BSYM = 0, for boost and cut.

7.5.6 VOLUME 2
The four volume 2 blocks are located at the end of the

tone/volume control. In addition to volume control (same
settings as volume 2) the balance and fader functions are
alsoperformedbyindividualattenuation offsets for the four
attenuators. The control range of these attenuators is
56 dB in steps of 1 dB and the additional steps of

−58.5 dB, −62 dB, −68 dB and a mute step.

7.5.7 RSA SELECTOR

7.5.3 VOLUME 1

The volume 1 control circuit follows the loudness circuit.
The control range of volume 1 is between +20 and −36 dB
in steps of 1 dB.

7.5.4 TREBLE

The output signal of the volume 1 control circuit is fed into
the treble control stage. The control range is between
+14 and −14 dB in steps of 2 dB. Fig.20 shows the control
characteristic with external capacitors of 10 nF.

The RSA selector provides the possibility to select an
alternative source for the rear channels. In this event rear
channels are only controlled by the volume 2 function.

7.5.8 CHIME ADDER
The chime adder circuit enables the chime input signal to

be summed with the left front and/or right front audio, or be
turned off.
