Audio FM processor for VHS hi-fi audio
TDA9610H
The headphone select block offers the possibility to
FUNCTIONAL DESCRIPTION
choose either the output select signal or four independent
audio signal modes (stereo, left, right and normal) for the
output stages HPOUTL and HPOUTR.
HPOUTL and HPOUTR, with common volume control for
L and R, is suitable for direct headphone drive.
The IC is intended for use within the audio FM system of
VHS video recorders. Three modes of operation can be
distinguished:
• Record mode
• Playback mode
• Loop-through mode.
DCOUTL and DCOUTR are intended for VU meter drive.
It is connected to the selected stereo audio input after the
volume control block. The output signal at
DCOUTL and DCOUTR is proportional to the square root
of the recorded audio signal (see Fig.3).
Switching and control of the three modes is done by the
I2C-bus.
Record mode
Playback mode
The audio signal, selected from the four stereo audio
inputs (EXT1L, EXT1R, EXT2L, EXT2R, CINL, CINR,
TUNL and TUNR), is fed to the volume control stage
(separate for left [L] and right [R]). The information for
LINOUT is, after summing of L and R, derived from either
one of the four stereo inputs or the volume control output
or one of the mono inputs (EXN1 and EXN2). After the
Low-Pass Filter (LPF) and signal compression in the noise
reduction (NR) and filter block the audio signal is available
at AFOUTL and AFOUTR. The compressed signal is now
FM modulated on a RF carrier in the PLL block. After
low-pass filtering and summation of both RF carriers
(L and R) the signal is available at FMOUT.
The two FM modulated RF carriers, present at the two
FMINL and FMINR inputs after being band-pass filtered,
are demodulated in the PLL block. The LF audio signal is
fed through a sample-and-hold circuit to suppress
head-switching noise. The demodulated audio signal is
available at AFOUTL and AFOUTR. The audio signal is
low-pass filtered and expanded in the noise reduction (NR)
and filter block. The resulting audio signal is available after
the output and headphone select blocks for all four output
stages (LINEL, LINER, MODOUT, HPOUTL, HPOUTR,
DCOUTL and DCOUTR). The functionality of the output
and headphone select blocks is identical to the record
mode. During playback DCOUTL and DCOUTR are
connected to the headphone select block.
The output select block offers the possibility to choose
eight different audio signal modes:
The functionality of the input and normal select blocks is
also identical to record mode (see Fig.3), which offers the
possibility to control (other) audio signals independently
for LINOUT (see Fig.4).
1. Stereo.
2. Left.
3. Right.
4. Mono.
Loop-through mode
5. Normal.
This mode is similar to the record mode (see Fig.3), except
for the FMOUT pin, which is inactive, and the RAF output
which is active LOW (see Fig.5).
6. Mixed stereo (stereo + LININ).
7. Mixed left (left + LININ).
8. Mixed right (right + LININ).
These audio signal modes are selectable for the output
stages LINEL, LINER and MODOUT. The standard audio
output is LINEL and LINER, e.g. for SCART output.
MODOUT is a mono audio output, with an
overload-protecting AGC, to drive an external
RF modulator.

Notes
1. The RAF bit can be overruled externally by applying a low-ohmic voltage to the RAF I/O (pin 14) either logic 0 or
logic 1 (0 or +5 V). The actual mode of the IC is determined by the level measured at this pin.
2. The two record modes are equal, only differing in their reaction to forcing RAF LOW at the RAF I/O pin; the status of
the IPAF bit determines whether the IC is switched to the playback or loop-through mode.

Notes
1. With bits NSH and NSL in combination with bit NSS the input signal is selected which is fed out at pin 47 (LINOUT).
With bit NSS set LOW a selection can be made between the four stereo line inputs (like the hi-fi input select). With
bit NSS set HIGH, bits NSH and NSL make a selection between four special select functions.
When a stereo input source is selected, both channels are added to obtain a mono output signal, then the output
(L + R)
signal at LINOUT is equal to:
--------------------
2
(L × Volume Left + R × Volume Right)
In the Volume mode the output signal is equal to:

HSF is set HIGH the headphone output has its own output select function switchable with bits HSL and HSR.
a) These special headphone selections are also active for the VU meter drive during playback.
2. HSF from select byte.

1. The audio distortion is measured with the HID pulse frequency set to 1 kHz (500 Hz input at pin 51). FM signal:
fm = 10 kHz; ∆f = 50 kHz. The distortion is measured with a 3 kHz 4th-order low-pass filter. The measured value at
1 kHz HID-pulse frequency is corrected with 26 dB in order to calculate the equivalent distortion at 50 Hz HID-pulse
frequency.

Audio FM processor for VHS hi-fi audio
Adjustment of VCO frequency
TDA9610H
Power-down mode
Set the TDA9610H in record mode (NTSC off), no audio
input signal.
To lower the dissipation in a stand-by situation, the 12 V
supply voltage at pin 19 (VDDA1) and pin 20 (VDDH) may be
switched off, with pins 19 and 20 ‘floating’. No low-ohmic
DC path to ground may be seen from pins 19 and 20,
because this will drain extra current from the 5 V supply via
these pins to ground.
Measure the frequency at FMOUT (pin 56) with a
frequency counter and use the VCO TEST modes
(see Section “Function byte”) to output only the channel of
interest.
Because of the fact that the I2C circuitry and the digital
outputs RAF, NTSC and XS are supplied via the 5 V
supply, no I2C settings will be lost and the output pins can
still be used.
Adjust the VCO frequencies to 1.4 MHz ±10 kHz and
1.8 MHz ±10 kHz by means of the potentiometers at
pin 64 (FADJL) and pin 53 (FADJR).
When NTSC is to be the main video standard, set
NTSC on and adjust to 1.3 MHz and 1.7 MHz for optimum
frequency accuracy.
For instance, XS can be used to drive external mute
transistors to mute the DC jump at the line outputs when
switching the 12 V supply.
Standard FM deviation and audio level
RAF I/O
Reference levels of frequency deviation and audio output
level are set by the resistor value at pin 24 (RVAR);
simultaneous for left, right, playback and record. Typical
resistor values can be calculated with equation:
The status of the I2C RAF bit is output at pin 14
(RAF = HIGH; record). This output can be used to switch
the audio FM head amplifier to playback and record. If
accurate fast switching of the TDA9610H is needed, this
pin can also be used as input. Thereby overruling the I2C
RAF bit. To make this possible the RAF output is current
limited.
2
∆f
------------------
50 kHz
Rtyp
=
× 2.2 kΩ
----------------------------------------------
A
---------------------------------------
400 mV (RMS)
When using the RAF pin as output, no more than 35 µA
(LOW) and 185 µA (HIGH) current may be drawn from this
pin to assure the mode of the TDA9610H is not changed.
Where:
∆f = reference FM deviation.
A = reference audio output level (1 kHz audio
frequency).
When using the RAF pin as input, the voltage source used
must be capable of delivering at least 345 µA (forced
HIGH; >3.5 V) or sinking at least 65 µA (forced
LOW; <1.5 V).
If adjustment for overall tolerance is needed, R has to be
made adjustable for the range 0.7Rtyp to 1.4Rtyp
.
Set the TDA9610H in playback. Use a HF test generator to
make a carrier of 1.4 MHz with the desired modulation and
input this signal at FMINL (pin 61) or before the band-pass
filter and measure the audio output level at LINEL (pin 27).

SOLDERING
applied to the substrate by screen printing, stencilling or
pressure-syringe dispensing before device placement.
Plastic quad flat-packs
BY WAVE
Several techniques exist for reflowing; for example,
thermal conduction by heated belt, infrared, and
vapour-phase reflow. Dwell times vary between 50 and
300 s according to method. Typical reflow temperatures
range from 215 to 250 °C.
During placement and before soldering, the component
must be fixed with a droplet of adhesive. After curing the
adhesive, the component can be soldered. The adhesive
can be applied by screen printing, pin transfer or syringe
dispensing.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 min at 45 °C.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder bath is
10 s, if allowed to cool to less than 150 °C within 6 s.
Typical dwell time is 4 s at 250 °C.
REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING
IRON OR PULSE-HEATED SOLDER TOOL)
Fix the component by first soldering two, diagonally
opposite, end pins. Apply the heating tool to the flat part of
the pin only. Contact time must be limited to 10 s at up to
300 °C. When using proper tools, all other pins can be
soldered in one operation within 2 to 5 s at between 270
and 320 °C. (Pulse-heated soldering is not recommended
for SO packages.)
A modified wave soldering technique is recommended
using two solder waves (dual-wave), in which a turbulent
wave with high upward pressure is followed by a smooth
laminar wave. Using a mildly-activated flux eliminates the
need for removal of corrosive residues in most
applications.
For pulse-heated solder tool (resistance) soldering of VSO
packages, solder is applied to the substrate by dipping or
by an extra thick tin/lead plating before package
placement.
BY SOLDER PASTE REFLOW
Reflow soldering requires the solder paste (a suspension
of fine solder particles, flux and binding agent) to be
