I2C-bus controlled BTSC stereo/SAP
decoder and audio processor
I
The composite input signal is fed to the input level
adjustment stage. The control range is from
−3.5 to +4.0 dB in steps of 0.5 dB. The subaddress
control 3 of Tables 5 and 6 and the level adjust setting of
Table 21 allows an optimum signal adjustment during the
set alignment. The maximum input signal voltage is
2 V (RMS).
TEREO DECODER
S
The output signal of the level adjustment stage is coupled
to a low-pass filter which suppresses the baseband noise
above 125 kHz. The composite signal is then fed into a
pilot detector/pilot cancellation circuit and into the MPX
demodulator. The main L + R signal passes a 75 µs fixed
de-emphasis filter and is fed into the dematrix circuit.
The decoded sub-signal L − R is sent to the stereo/SAP
switch. To generate the pilot signal the stereo demodulator
uses a PLL circuit including a ceramic resonator.
The stereo channel separation is adjusted by an automatic
procedure to be performed during set production. For a
detailed description see Section “Adjustment procedure”.
The stereo identification can be read by the I2C-bus
(see Table 2). Two different pilot thresholds
(data STS = 1; STS = 0) can be selected via the I2C-bus
(see Table 19).
DEMODULATOR
SAP
The composite signal is fed from the output of the input
level adjustment stage to the SAP demodulator circuit
through a 5fH (fH= horizontal frequency) band-pass filter.
The demodulator level is automatically controlled.
The SAP demodulator includes internal noise and field
strength detectors that mute the SAP output in the event of
insufficient signal conditions. The SAP identification signal
can be read by the I2C-bus (see Table 2).
Fig.3 Pin configuration (SDIP-version).

WITCH
S
The stereo/SAP switch feeds either the L − R signal or the
SAP demodulator output signal via the internal dbx noise
reduction circuit to the dematrix/switching circuit. Table 12
shows the different switch modes provided at the output
pins LOR and LOL.
Page 9

dbx DECODER
The circuit includes all blocks required for the noise
reduction system in accordance with the BTSC system
specification. The output signal is fed through a 73 µs fixed
de-emphasis circuit to the dematrix block.
I
NTEGRATED FILTERS
The filter functions necessary for stereo and SAP
demodulation and part of the dbx filter circuits are provided
on-chip using transconductor circuits. The required filter
accuracy is attained by an automatic filter alignment
circuit.
Audio processor
ELECTOR
S
The selector allows selecting either the internal line out
signals LOR or LOL (dematrix output) or the external line
in signals LIR and LIL and combines the left and right
signals in several modes (see Tables 5 and 6 for
subaddress and Table 11 for data). The input signal
capability of the line inputs (LIR/LIL) is 2 V (RMS).
The output of the selector is AC-coupled to the automatic
volume level control circuit via pins SOR/SOL and
AVR/AVL to avoid offset voltages.
UTOMATIC VOLUME LEVEL CONTROL
A
The automatic volume level stage controls its output
voltage to a constant level of typically 200 mV (RMS) from
an input voltage range of 0.1 to 1.1 V (RMS). The circuit
adjusts variations in modulation during broadcasting and
due to changes in the programme material. The function
can be switched off. To avoid audible ‘plops’ during the
permanent operation of the AVL circuit a soft blending
scheme has been applied between the different gain
stages. A capacitor (4.7 µF) at pin CAV determines the
attack and decay time constants. In addition the ratio of
attack and decay time can be changed via I2C-bus
(see Table 15). At power on, the discharged 4.7 µF
capacitor at CAV must be loaded by the internal decay
current. If AVL is chosen, this would result in an attenuated
AVL gain for about 10 seconds after poweron. This can be
speeded up by choosing via I2C-bus an increased charge
current (about 10 times higher) for about the first
2 seconds after power on (see Table 6, CCD bit in
control 1 and Table 18).
TDA9852
E
FFECTS
The audio processor section offers the following mode
selections: linear stereo, pseudo stereo, spatial stereo and
forced mono.The spatial mode provides an antiphase
crosstalk of 30% or 52% (switchable via I2C-bus;
see Table 10).
V
OLUME/LOUDNESS
The volume control range is from +16 dB to −71 dB in
steps of 1 dB and ends with a mute step (see Table 8).
Balance control is achieved by the independent volume
control of each channel. The volume control blocks
operate in combination with the loudness control. The filter
is linear when maximum gain for volume control is
selected. The filter characteristic changes automatically
over a range of 28 dB down to a setting of −12 dB.
At −12 dB volume control the maximum loudness boost is
obtained. The filter characteristic is determined by external
components. The proposed application provides a
maximum boost of 17 dB for bass and 4.5 dB for treble.
The loudness may be switched on or off via I2C-bus
control (see Table 9). The left and right volume control
stages include two independent zero crossing detectors.
A change in volume is automatically activated but not
executed. The execution is enabled at the next zero
crossing of the signal. If a new volume step is activated
before the previous one has been processed, the previous
value will be executed first, and then the new value will be
activated. If no zero crossing occurs the next volume
transmission will enforce the last activated volume setting.
The zero crossing is realized between adjoining steps and
between any steps, but not from any step to mute. In this
case the GMU bit is needed to use. In case only one
channel has to be muted, two steps are necessary.
The first step is a transmission of any step to −71 dB and
the second step is the−71 dB step to mute mode. The step
of −71 dB to mute mode has no zero crossing but this is
not relevant.

Philips SemiconductorsPreliminary specification
I2C-bus controlled BTSC stereo/SAP
decoder and audio processor
MUTE
The mute function can be activated independently with last
step of volume control at the left or right output. By setting
the general mute bit GMU via the I2C-bus all outputs are
muted. All channels include an independent zero cross
detector. The zero crossing mute feature can be selected
via bit TZCM:
TZCM = 0: forced mute with direct execution
TZCM = 1: execution in time with signal zero crossing.
In the zero cross mode a change in the GMU polarity is
activated but not executed. The execution is enabled at
the next zero crossing of the signal. To avoid a large delay
of mute switching, when very low frequencies are
processed, or the output signal amplitude is lower than the
DC offset voltage, the following I
needed:
a first transmission for mute execution
a second transmission about 100 ms later, which must
switch the zero crossing mode to forced mute
(TZCM = 0)
a third transmission to reactivate the zero crossing
mode (TZCM = 1). This transmission can take place
immediately, but must follow before the next mute
execution.
Adjustment procedure
COMPOSITE INPUT LEVEL ADJUSTMENT
Feed in from FM demodulator the composite signal with
100% modulation (25 kHz deviation) L + R; fi= 300 Hz.
Set input level control via I2C-bus monitoring line out
(500 mV ±20 mV). Store the setting in a non-volatile
memory.
• Start adjustment by transmission ADJ = 1 in register
ALI3; the decoder will align itself
• After 1 second minimum stop alignment by transmitting
ADJ = 0 in register ALI3 read the alignment data by an
2
I
C-bus read operation from ALR1 and ALR2
(see Chapter “I2C-bus protocol”) and store it in a
non-volatile memory; the alignment procedure
overwrites the previous data stored in ALI1 and ALI2
• Disconnect the capacitors of external inputs from
ground.
M
ANUAL ADJUSTMENT
Manual adjustment is necessary when no dual tone
generator is available (e.g. for service).
• Spectral and wideband data have to be set to 10000
(middle position for adjustment range)
• Composite input L = 300 Hz; 14% modulation
• Adjust channel separation by varying wideband data
• Composite input L = 3 kHz; 14% modulation
• Adjust channel separation by varying spectral data
• Iterative spectral/wideband operation for optimum
adjustment
• Store data in non-volatile memory.
IMING CURRENT FOR RELEASE RATE
T
Due to possible internal and external spreading, the timing
current can be adjusted via I2C-bus, see Table 20, as
recommended by dbx.
• Capacitors of external inputs LIL and LIR must be
grounded at EIL and EIR
• Composite input signal L = 300 Hz, R = 3.1 kHz,
14% modulation for each channel; volume gain +16 dB
via I2C-bus

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
“IC Package Databook”
SDIP
OLDERING BY DIPPING OR BY WA VE
S
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
EPAIRING SOLDERED JOINTS
R
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
QFP
REFLOW SOLDERING
Reflow soldering techniques are suitable for all QFP
packages.
The choice of heating method may be influenced by larger
plastic QFP packages (44 leads, or more). If infrared or
vapour phase heating is used and the large packages are
not absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For more
information, refer to the Drypack chapter in our
Reference Handbook”
(order code 9398 652 90011).

“Quality
(order code 9398 510 63011).
TDA9852
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary from
50 to 300 seconds depending on heating method. Typical
reflow temperatures range from 215 to 250 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheat for 45 minutes at 45 °C.
WAVE SOLDERING
Wave soldering is not recommended for QFP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
If wave soldering cannot be avoided, the following
conditions must be observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
• The footprint must be at an angle of 45° to the board
direction and must incorporate solder thieves
downstream and at the side corners.
Even with these conditions, do not consider wave
soldering the following packages: QFP52 (SOT379-1),
QFP100 (SOT317-1), QFP100 (SOT317-2),
QFP100 (SOT382-1) or QFP160 (SOT322-1).
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured. Maximum permissible solder
temperature is 260 °C, and maximum duration of package
immersion in solder is 10 seconds, if cooled to less than
150 °C within 6 seconds. Typical dwell time is 4 seconds
at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
R
EPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
