TDA9614H
3. SAP (SAP input).
Audio I/O switching
6.1.1
This setting enables simultaneous recording of the
NTSC SAP signal on the linear track and TUNER
stereo on the audio FM track. When receiving a
NICAM audio signal, the linear audio can be used as a
‘backup’ track when received television signals are
weak.
INPUT SELECT (INPUTSEL)
For the audio FM circuitry eight different audio signals can
be selected. The selection made here for hi-fi is also
available for the linear audio circuitry.
1. TUNER (stereo input; internal tuner of VCR).
4. TUNER LEFT (left channel [language 1] of TUNER
input).
2. CINCH (stereo input; connection to hi-fi set).
3. EXT1 (stereo input; TV SCART1).
When receiving dual language transmissions the main
language (language 1) can be recorded on linear
audio. Note that if the SAP input is not used it can be
connected to the right TUNER channel, enabling
language selection for linear audio.
4. EXT2 (stereo input; decoder, 2nd VCR SCART2).
5. EXT3 (stereo input; front CINCH for e.g. camcorder).
6. SAP (mono input; ‘Second Audio Program’ audio
carrier for NTSC or conventional FM carrier with
NICAM reception).
6.1.3
7. NORMAL (linear audio; [playback] signal of linear
audio).
The volume controls are mainly intended for level
adjusting of the audio signals to be recorded on the hi-fi
track, however using the ‘VOLUME’ setting in the Normal
Select it can also be used to control linear audio. The
volume controls have a control range of +14 dB to −49 dB
in 1 dB steps and a full mute. Because the volume controls
are I2C-bus controlled their actual behaviour is defined by
the VCR’s software. For instance user control can be
‘volume only’, ‘left + right’, ‘volume + balance’ or the
setting can be defined by a ‘digital AGC’ software loop
using the signals at the DC (VU meter) outputs.
When inserting a new video signal in an old
audio/video recording the hi-fi audio track is erased.
This setting can keep the current audio available on
the hi-fi track by copying the (playback) linear audio
signal to the hi-fi track during video insert.
8. EXT3/ST (input mix; mono EXT3 on left, mono hi-fi on
right channel).
For linear audio use see Section 6.1.2.
6.1.2
NORMAL SELECT (NORMSEL)
The linear audio level can be controlled by an AGC circuit,
which can be switched off when desired. In most cases the
AGC should be used at all settings of the Normal Select
except for ‘VOLUME’.
For linear audio four settings can be selected:
1. INPUTSEL (mono signal from input select).
This is the ‘standard’ setting. The signal source
selected with the input select is led to the linear audio
circuit. The linear audio AGC should be switched on.
6.1.4
2. VOLUME (mono signal from [hi-fi] volume control).
AUDIO FM OUTPUT MUTE (AFOMUTE);
NORMAL OUTPUT MUTE (NOMUTE)
The audio output signal of the audio FM circuit can be
muted with AFOMute, the linear output signal can be
muted using NOMute. If one of these signals is not used
as an output (or input) signal it is best muted to further
minimize crosstalk.
The signal source selected with the input select has
now volume control, the linear audio AGC should be
switched off. This setting is for use with ‘audio
dubbing’: inserting a new audio signal on the linear
track in an old audio/video recording. A special audio
dubbing feature is now possible by selecting ‘input mix’
EXT3/ST in the input select. This setting enables us to
use the VCR as a mixer console: an audio source
connected to EXT3 (front CINCH) can be adjusted and
mixed together with the original hi-fi playback signal,
using the left (EXT3) and right (hi-fi playback) volume
controls.

VOLUME L/R; AGC
6.1.5
OUTPUT SELECT (OUTSEL)
This block is the ‘main’ output select function, possibly
functional on all outputs. Each output however has some
means to override this selection for its own output signal,
to implement extra features. Eight selections are possible
and they are shown in Table 1.

Note
1. STEREO is the ‘standard’ setting, LEFT and RIGHT are for language selection. Using the tuner as input or output
signal (record or loop-through of audio FM) the VCR can automatically switch from stereo to left (language 1) when
a ‘dual language’ transmission is received. If the VCR is in playback mode and no hi-fi track is present (checking bit
AFOM via the I2C-bus or using the level at pin 11) the VCR can switch the output select to NORMAL (or let the IC
do this automatically by setting bit AUTN). If a hi-fi track is present the user may want to switch to LEFT and RIGHT
if the recording made was a ‘dual language’ recording.
Furthermore the user may want to switch from a hi-fi selection to NORMAL, e.g. when a complete audio remix has
been created on the linear track using ‘audio dubbing’ (see Section 6.7). ‘Audio dubbing’ can also be used to
re-record the linear track with e.g. only commentary. Combined playback of this commentary together with the
original hi-fi sound is then possible by means of a mix mode.
6.1.6
RF CONVERTER MUTE (RFCMUTE)
The RFC output is a mono output derived from the output select, its output signal can be muted.
6.1.7
LINE SELECT (LINESEL)
The line output select is normally connected to both CINCH (hi-fi set) and television (SCART1). Normally the audio signal
from the output select will be available at this output, but three extra selections are possible and they are shown in
Table 2.

Notes
1. A signal from a source at EXT2 (laser disc or second VCR) can be connected to a television set at line out. Because
this is a direct connection from the input to the line output buffers it is fully independent of any mode setting of the
IC. Connection of a ‘Pay-TV’ decoder box to EXT2 and using this selection together with selecting EXT1 in the
decoder select enables combined use of the decoder box by both TV and VCR. In Europe, use of the SCART
connector ‘status line’ can automatize this switching.
2. Direct audio connection from input EXT3. If the line 2 outputs and EXT3 inputs are not used for external connections
a built-in karaoke unit or sound processor can be inserted between line 2 and EXT3.

STEREO can be made.
DECODER SELECT (DECODESEL)
The line 2 output is normally connected to a decoder box
or e.g. a second VCR (SCART2). Normally the audio
signal from the output select will be available at this output,
but three extra selections are shown in Table 3.

From here on the signal goes to the output select and (in
the event of record mode) to the record equalizer. The
record equalizer is a non-inverting amplifier with a gain of
+12 dB, consisting of an opamp with feedback resistors,
and acts as a pre-correction filter for the tape and head
characteristics. The inverting input of the opamp is
connected to pin 31 (RECEQ), its output to pin 33
(RECOUT). The circuit externally connected between
pin 31 and ground defines the transfer of the record
( 1200 + Z )
equalizer with equation: A = 3.98 × -----------------------------Z
Notes
1. Enables the use of a decoder box (connected to line 2
[EXT2]) by the VCR.
2. Decoder box connection to television set
(See Section 6.1.7).
6.1.9
HEADPHONE SELECT (HPSEL)
The headphone output will normally carry the output select
signal, however three more selections are possible and
shown in Table 4.
Table 4
Where: Z is the complex impedance of the external circuit.
Two equalizings can be used, switching additional circuitry
to ground with pin 30 (EQSW) in long play or extended
play (I2C-bus: LP = 1).
Extra headphone select possibilities
SELECTION
RECORD/LOOP-THROUGH
The signal selected with the normal select can be level
controlled in the AGC block. If wanted this AGC can be
switched off using bit AGCN. The audio signal is thereafter
DC decoupled using a capacitor between pin 29 (LINOUT)
and pin 28 (LININ).
DESCRIPTION

DESCRIPTION
LEFT(1)

RIGHT(1)

Instead of the hi-fi circuit, linear audio has two
loop-through modes:
NORMAL

recording by ‘audio dubbing’
• Loop-through playback
• Loop-through record.
Note
The only difference between Loop-through record and
record is the RECOUT output, which is muted.
1. The selections LEFT and RIGHT make it possible to
select a different language for the headphone as for
the line outputs. A possible implementation is to invert
always a language selection made at the output select.
6.1.10
The LINREC output (pin 32) is used to drive the external
high-voltage switch and possibly the bias oscillator. The
LINREC voltage has a small internal delay to be
non-overlapping with the internal switching to playback
mode. This ensures that no bias voltage will appear at the
PBIN input while the IC is in playback mode.
HEADPHONE VOLUME
The headphone volume control has a control range of
+16 dB to −47 dB in 1 dB steps and a full mute.
6.2.2
6.1.11
DC SELECT (DCSEL)
The signal coming from the head is amplified and can be
level controlled in 16 steps of 1 dB. This setting can be
used to adjust for spread or nominal difference in head
output level. Afterwards, the signal is frequency corrected
in the playback equalizer. This equalizer includes the two
standard VHS equalizing settings of 3180 and 120 µs
The VU meter output is normally connected to the
headphone select, but can also be switched to STEREO
(hi-fi stereo, before the output select). When using the
VU meter output signal to implement a ‘digital AGC’ (read
the level at the DC output, and adjust the VOLUME L/R
controls accordingly) it is necessary to have information of

(standard play: LP = 0) and 3180 and 170 µs (Long Play:
LP = 1).
low-pass filtered audio signal is expanded in the noise
reduction.
The signal is DC decoupled and routed to the output select
via pins 29 and 28. When switching to or from playback
the signal should be muted shortly using the Normal
Output Mute (NOM) to prevent audible clicks caused by
offset differences of the playback amplifier and AGC.
If the left channel carrier at FMIN falls below the mute level
of 4.2 mV (RMS value) the audio signal is muted in front of
the low-pass filter. This is achieved by comparing the left
channel level detector signal with an internal reference.
The mute timing is fixed by a capacitor at the CMUTE pin.
If the level at CMUTE rises above a certain threshold, the
PBMUTE bit is set. This will mute the audio signal. If bit
AUTN has been set, the output selection will automatically
switch to NORMAL mode. The left channel level detector
output is also available at pin ENVOUT. An AGC
correction voltage is added at this pin, such that the
ENVOUT voltage indicates the left channel FM-carrier
level even within the AGC-range. The ENVOUT voltage
can be used for auto-tracking of the FM-audio heads.

6.3.1
Audio FM circuits
RECORD/LOOP-THROUGH
After low-pass filtering and signal compression in the
Noise Reduction (NR) the audio signal is available at
AFNL and AFNR. Through a DC-decoupling capacitor the
compressed audio signal is fed to an audio clipper at
AFML and AFMR. Subsequently, the audio signal is
FM-modulated on a RF-carrier using an integrated
current-controlled oscillator (CCO). Each CCO (L and R)
requires an external resistor (RCCOL/R) for temperature
stability. Through automatic calibration both the oscillator
centre frequency and FM-deviation are adjusted. After
low-pass filtering and summation of the two RF-carriers,
the FM signal is available at FMOUT during record. During
loop-through the FMOUT pin is inactive.
In the event of drop-outs in the incoming FM signal, the left
channel level detector is also used to activate the
sample-and-hold. This drop-out cancellation is only active
if bit DOC has been set.
6.3.3
By means of bit CALS the two integrated oscillators and
bandpass filters can be calibrated in Loop-Through (LT) or
record (REC) mode. Normally this will be done after
start-up of the VCR. After setting of bit CALS the
calibration procedure is automatically executed as shown
in Fig.4. The calibration starts at the first negative edge of
HID after CALS has been set. During the LOW period of
HID (20 ms for PAL) the number of oscillator cycles is
compared to a certain value stored in a Read Only Memory
(ROM).
The RAF pin reflects the status of the RAF-bit when it is
used as output pin. In this case it is meant to switch the
head amplifier between record and playback position. It
can also be used as an input pin to overrule the RAF-bit
thereby forcing the IC in record or playback/loop-through
position.
6.3.2
PLAYBACK
The two FM modulated RF carriers, presented at FMIN,
are fed to an AGC circuit. The AGC operates on the peak
level of the added BPF output signals. As a result, the input
signal of the BPFs is kept constant for FMIN voltages
>30 mV (RMS value) both carriers added. In this way the
dynamic range of the integrated BPFs is optimally used
over a large input signal range. Subsequently, the
RF carriers are bandpass filtered using two integrated
BPFs. These bandpass filters are automatically calibrated
as described in Section 6.3.3. An external resistor (RBPF)
is required for temperature stability.
Therefore, the final oscillator frequency is proportional to
the inverse of the HID LOW-time. This means that an error
of 1 µs in the HID LOW-time will result in an additional
frequency error of approximately 100 Hz. The maximum
number of required HID cycles for one complete oscillator
calibration is six, which is equal to 240 ms.
After both oscillators have been calibrated the bandpass
filters are calibrated using the right channel oscillator as
reference frequency generator (1.6 MHz for PAL). This will
take <10 ms.
Bit CALR is set to 1 if the calibration has been executed
successfully. CALR is 0 if:
The filtered input signals are fed to a limiter. The limiter
output signal is demodulated by means of a
PLL demodulator. The LF audio signal is fed through a
sample-and-hold circuit to suppress head-switching noise.
The demodulated audio is available at AFML and AFMR.
Through a decoupling capacitor the audio signal is applied
to an audio low-pass filter at AFNL and AFNR. The

• A Power-On Reset (POR) has occurred.
• The calibration is running.
• The initial oscillator and bandpass frequencies are too

WARNING: A change of PB to REC, LT to REC and
PAL to NTSC should not be combined in one transmitted
byte. The PAL to NTSC transition should be preceded by
the PB to REC or LT to REC transition.
WARNING: the IC should not be calibrated in a test or

The TDA9614H is controlled via the 2-wire I2C-bus, in
accordance with the I2C-bus specification. As slave
receiver for programming there is one module address,
with R/W bit = 0, a subaddress byte and eight data bytes.
If more than one data byte follows the subaddress, these
bytes are stored in the successive registers by the
automatic address increment feature. As slave transmitter
(R/W bit = 1) there is one read byte.
PAL/NTSC MODE
Depending on bit NTSC the IC is calibrated in PAL or
NTSC mode using bit CALS. After an automatic calibration
the oscillator frequencies can be switched between PAL
and NTSC using bit NTSC. This centre frequency shift is
done without automatic calibration. During playback (PB)
or loop-through (LT) a change in bit NTSC will
automatically calibrate the bandpass filters again. This will
take <10 ms.

1. The RAF bit can be overruled externally by applying a low-ohmic voltage to the RAF I/O (pin 12) 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, enabling fast switching
between record and playback/loop-through.
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.

SELECTED INPUT SOURCE
Notes
1. With bits IS2 to IS0, the stereo input signal is selected which is led to the hi-fi processing. One out of five stereo
sources can be selected. The five stereo inputs differ in their connectivity; with bits NS1 and NS0 tuner left
(TUNL; pin 2) can be selected as linear audio input source, with bits LOS1 and LOS0 Normal, Ext2 and Ext3 are
directly connectable to Line out and to DOS1 and DOS0 Tuner, Ext1 and Ext3 are directly connectable to decoder
out (2nd Line Out).
2. Remark: when using the selections Normal or Dub Mix be aware of signal loops (which should be avoided) because
this can lead to large audio oscillations.
3. The selection Dub Mix is a special function in which a mono signal derived from the Ext3 inputs
(1⁄2EXT3L + 1⁄2EXT3R) is led to the left input and a mono signal derived from the audio FM output (1⁄2L + 1⁄2R) is led
to the right input channel. This function can be used for audio dubbing using the volume controls as a mixing desk.

and LINER), RFCOUT (pin 18), decoder out (LINE2L and LINE2R), headphone out (HPOUTL and HPOUTR) and
DC out (DCOUTL and DCOUTR). However line out can be overruled by bits LOS1 and LOS0; decoder out can be
overruled by bits DOS1 and DOS0, headphone out (and DC out) can be overruled by bits HSL and HSR and DC out
can be overruled by bit DCS.
Remark: if AUTN = 1 (see Section 6.11) the output select modes stereo, left and right will be forced to normal as long
as the audio FM circuit is in playback mode and the internal PB mute signal is generated (no hi-fi track on tape). The

auto normal
Output select is switched to normal, when no hi-fi tracks are found in

Note
1. When the audio FM circuit is in playback and there is no FM input signal (playback of a conventional recording) the
audio FM circuitry is muted. If this situation occurs and AUTN = 1 the selections stereo, left or right in the output
select (OSR, OSL and OSN) are overridden and the selection normal is made. This means that linear audio is the
output signal for as long as the internal playback mute is active. The status of this internal mute signal can be read
by bit PAFM (see Section 6.13).

Note
1. When CALS is made logic 1 after being logic 0 the IC performs an automatic frequency calibration of the modem
CCOs and the built-in bandpass filters (BPFs). During calibration, the IC should be in record or loop-through mode.
The calibration takes <500 ms and uses the HID input (25 Hz in PAL mode or 30 Hz in NTSC mode) as the reference
frequency. The bit CALR (see Section 6.13) can be read to check if the calibration has been completed successfully.

calibrated
IC has been calibrated successfully.
Note
1. If CALR = 0, bandpass filters and oscillators have not been calibrated successfully. When an automatic calibration
is started by bit CALS, the end of the calibration cycle can be checked via this bit. If for some reason a successful
calibration can not be made within the available adjustment range, e.g. if no HID signal is available, CALR will remain
logic 0. After calibration the adjustment will be held for as long as the digital supply voltage (VDDD) is available.

PAFM
MODE
DESCRIPTION
0
AFM available
Audio FM signal is detected at FM input.
1
no AFM carrier
No audio FM signal detected; hi-fi processing is muted.
Note
1. When the hi-fi processing is in playback mode but no Audio FM input signal is found, the IC generates an internal
mute signal which mutes the noise signal coming from the demodulators. The status of this mute signal can be read
via bit PAFM. This signal however is only valid with the hi-fi circuit in playback (RAF = 0 and IPAF = 0).

DESCRIPTION

POR generated
POR pulse is generated since last read.
Note
1. When the IC is switched on, or a power dip occurs on the digital supply (VDDD) line, a Power-on Reset signal is
generated which resets the IC's I2C-bus registers and the auto-calibration circuit. If such a situation has occurred
after the last time the read byte has been read, bit POR = 1. After reading the read byte POR is reset to logic 0.

1. Using AGC on (AGCN = 0) and NormSel set to volume mode. The AGC gain is 1 dB higher for audio signals below
the AGC clip level (specified value of AGC clip level does not change).
Using AGC off (AGCN = 1) and NormSel not set to volume mode, the output signal is 1 dB lower (1 dB below the
specified value).

1. HID pulse frequency set to 1 kHz. Unmodulated carrier at FMIN input with 135° phase step.
2. The audio distortion is measured with the HID pulse frequency set to 1 kHz (fi = 500 Hz). 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.

12.1
TDA9614H
12.2
RAF I/O (pin 12)
The status of the I2C RAF bit is output (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 TDA9614H 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.
The external resistors to ground at pins RCCOL, RCCOR,
RBPF and RFIX must have a tolerance of 5%. This is
necessary to guarantee correct functioning of the IC. The
temperature coefficient of the external resistors at
RCCOL, RCCOR and RBPF have a direct influence on the
related frequencies of the on-chip oscillators and
bandpass filters.
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 that the mode of the TDA9614H is not
changed.
When using the RAF pin as input, the voltage source used

TDA9614H
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.
14 SOLDERING
14.1
14.1.1
Plastic quad flat packages
BY WAVE
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.
14.1.3
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.
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.
14.1.2
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
applied to the substrate by screen printing, stencilling or
pressure-syringe dispensing before device placement.
