Single/multistandard VIF/SIF-PLL and
FM-PLL/AM demodulators
FUNCTIONAL DESCRIPTION
The integrated circuit comprises the functional blocks as
shown in Fig.1:
• Vision IF amplifier and VIF AGC detector
• Tuner AGC
• Frequency Phase Locked Loop detector (FPLL)
• VCO, Travelling Wave Divider (TWD) and AFC
• Video demodulator and amplifier
• Sound IF amplifier and SIF AGC
• Single reference QSS mixer
• AM demodulator
• FM-PLL demodulator
• Audio Frequency (AF) signal processing
• Internal voltage stabilizer.
Vision IF amplifier and VIF AGC detector
The vision IF amplifier consists of three AC-coupled
differential amplifier stages. Each differential stage
comprises a feedback network controlled by emitter
degeneration.
The AGC detector generates therequired VIF gain control
voltage for constant video output by charging/discharging
the AGC capacitor. Therefore for negative video
modulation the sync level and for positive video
modulation the peak white level of the video signal is
detected. In order to reduce the reaction time for positive
modulation, where a very large time constant is needed,
an additional level detector increases the discharging
current of the AGC capacitor (fast mode) in the event of a
decreasing VIF amplitude step. The additional level
information is given by the black-level detector voltage.
Tuner AGC
The AGC capacitor voltage is converted to an internal
IF control signal, and is fed to the tuner AGC to generate
the tuner AGC output current at pin TAGC (open-collector
output). The tuner AGC takeover point can be adjusted at
pin TADJ. This allows to match the tuner to the SAW filter
in order to achieve the optimum IF input level.
Frequency Phase Locked Loop detector (FPLL)
The VIF-amplifier output signal is fed into a frequency
detector and into a phase detector via a limiting amplifier.
During acquisition the frequency detector produces a
DC current proportional to the frequency difference
between the input and the VCO signal. After frequency
lock-in the phase detector produces a DC current
TDA9817; TDA9818
proportionalto the phase differencebetween the VCO and
the input signal. The DC current of either frequency
detector or phase detector is converted into a DC voltage
viathe loop filter, whichcontrols the VCO frequency.Inthe
event of positive modulated signals the phase detector is
gated by composite sync in order to avoid signal distortion
for overmodulated VIF signals.
VCO, Travelling Wave Divider (TWD) and AFC
The VCO operates with a resonance circuit (with L and C
in parallel) at double the picture carrier frequency. The
VCO is controlled by two integrated variable capacitors.
The control voltage required to tune the VCO from its
free-running frequency to actually double the picture
carrier frequency is generated by the frequency-phase
detector (FPLL) and fed via the loop filter to the first
variable capacitor. This control voltage is amplified and
additionally converted into a current which represents the
AFC output signal. At centre frequency the AFC output
current is equal to zero.
For TDA9818: the VCO centre frequency can be
decreased (required for L accent standard) by activating
an additional internal capacitor. This is achieved by using
the L accent switch. In this event the second variable
capacitor can be controlled by a variable resistor at the
L accentswitchforsettingtheVCOcentrefrequencytothe
required L accent value.
The oscillator signal is divided by 2 with a TWD which
generates two differential output signals with a 90 degree
phase difference independent of the frequency.
Video demodulator and amplifier
The video demodulator is realized by a multiplier which is
designed for low distortion and large bandwidth. The
vision IF input signal is multiplied with the ‘in phase’ signal
of the travelling wave divider output. In the demodulator
stage the video signal polarity can be switched in
accordance with the TV standard.
The demodulator output signal is fed via an integrated
low-pass filter for attenuation of the carrier harmonics to
the video amplifier. The video amplifier is realized by an
operational amplifier with internal feedback and high
bandwidth. A low-pass filter is integrated to achieve an
attenuation of the carrier harmonics for B/G and
L standard. The standard dependent level shift in this
stage delivers the same sync level for positive and
negative modulation. The video output signal at pin CVBS
is 1.1 V (p-p) for nominal vision IF modulation, in order to
achieve 1 V (p-p) at sound trap output.

Single/multistandard VIF/SIF-PLL and
FM-PLL/AM demodulators
Sound IF amplifier and SIF AGC
The sound IF amplifier consists of two AC-coupled
differential amplifier stages. Each differential stage
comprises a controlled feedback network provided by
emitter degeneration.
The SIF AGC detector is related to the SIF input signal
(average level of AM or FM carrier) and controls the SIF
amplifier to provide a constant SIF signal to the
AM demodulator and single reference QSS mixer. At
L standard (AM sound) the SIF AGC reaction time is set to
‘slow’ for nominal video conditions. But with a decreasing
VIF amplitude step the SIF AGC is set to ‘fast’ mode
controlled by the VIF AGC detector. In FM mode this
reaction time is always ‘fast’.
Single reference QSS mixer
The single reference QSS mixeris realized by a multiplier.
The SIF amplifier output signal is fed to the single
reference QSS mixer and converted to intercarrier
frequency by the regenerated picture carrier (VCO). The
mixer output signal is fed via a high-pass for attenuation of
the video signal components to the output pin QSS. With
this system a high performance hi-fi stereo sound
processing can be achieved.
For a simplified application without a sound IF SAW filter
the single reference QSS mixer can be switched to the
intercarrier mode byconnecting pin SIF2 to ground. In this
mode the sound IF passes the vision IF SAW filter and the
composite IF signal is fed to the single reference QSS
mixer. This IF signal is multiplied with the 90 degree TWD
output signal for converting the sound IF to intercarrier
frequency. This composite intercarrier signal is fed to the
output pin QSS, too. By using this quadrature detection,
the low frequency video signals are removed.
AM demodulator
The AM demodulator is realized by a multiplier. The
modulated SIF amplifier output signal is multiplied in
phase with the limited (AM is removed) SIF amplifier
output signal. The demodulator output signal is fed via an
integrated low-pass filter for attenuation of the carrier
harmonics to the AF amplifier.
TDA9817; TDA9818
FM-PLL demodulator
The FM-PLL demodulator consists of a limiter and an
FM-PLL. The limiter provides the amplification and
limitation of the FM sound intercarrier signal. The result is
high sensitivity and AM suppression. The amplifier
consists of 7 stages which are internally AC-coupled in
order to minimize the DC offset.
Furthermore the AF output signal can be muted by
connecting a resistor between the limiter input pin FM
and ground.
TheFM-PLL consists of anintegrated relaxation oscillator,
an integrated loop filter and a phase detector. The
oscillator is locked to the FM intercarrier signal, output
from the limiter. As a result of locking, the oscillator
frequency tracks with the modulation of the input signal
and the oscillator control voltage is superimposed by the
AF voltage. The FM-PLL operates as an FM demodulator.
Audio Frequency signal processing
The AF amplifier consists of two parts:
1. The AF pre-amplifier for FM sound is an operational
amplifier with internal feedback, high gain and high
common mode rejection. The AF voltage from the
PLL demodulator, by principle a small output signal, is
amplified by approximately 33 dB. The low-pass
characteristicoftheamplifierreducestheharmonicsof
the intercarrier signal at the sound output terminal
pin V
sound is applied. An additional DC control circuit is
implemented to keep the DC level constant,
independent of process spread.
2. The AF output amplifier (10 dB) provides the required
output level by a rail-to-rail outputstage. This amplifier
makes use of an input selector for switching to AM,
FM de-emphasis or mute state, controlled by the
standard switching voltage and the mute switching
voltage.
Internal voltage stabilizer
The bandgap circuit internally generates a voltage of
approximately 1.25 V, independent of supply voltage and
temperature. A voltage regulator circuit, connected to this
voltage, produces a constant voltage of 3.6 V which is
used as an internal reference voltage.

Notes
1. Values of video and sound parameters are decreased at VP= 4.5 V.
2. This parameter is not tested during production and is only given as an application information for designing the
television receiver.
3. Loop bandwidth BL = 70 kHz (natural frequency fn= 12 kHz; damping factor d ≈ 3; calculated with sync level within
gain control range). Resonance circuit of VCO: Q0> 50; C
approximately 2.7 V).
4. Temperature coefficient of external LC circuit is equal to zero.
5. V
i(VIF)(rms)
= 10 mV; ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture

6. VIF signal for nominal video signal.
7. The leakage current of the AGC capacitor should not exceed 1 µA at B/G standard, respectively 10 nA current at
L standard. Larger currents will increase the tilt.
8. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin CVBS). B=5MHz

“CCIR 567”

12. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.9. The AFC-steepness can be changed by the resistors at pin AFC.

14. Source impedance: 2.3 kΩ in parallel to 12 pF (SAW filter); fIF= 38.9 MHz.
15. Without using an SIF SAW filter the mixer can be switched to intercarrier mode by connecting pin SIF1 and/or
pin SIF2 to ground. In this mode the SIF passes the VIF SAW filter and IF intercarrier levels are depending on the
sound shelf of the VIF SAW filter. The intercarrier output signal at pin QSS can becalculated by thefollowing formula

a) Second IF input level 10 mV (RMS value).
17. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV (RMS) (Rx=0Ω). By using
Rx= 470 Ω the AF output signal is attenuated by 6 dB [250 mV (RMS)]. For handling a frequency deviation of more
than 53 kHz the AF output signal has to be reduced by using Rx in order to avoid clipping (THD < 1.5%). For an
FM deviation up to 100 kHz an attenuation of 6 dB is recommended with Rx= 470 Ω.
18. The leakage current of the decoupling capacitor (2.2 µF) should not exceed 1 µA.
19. For all S/N measurements the used vision IF modulator has to meet the following specifications:
a) Incidental phase modulation for black-to-white jump less than 0.5 degrees
b) QSS AF performance, measured with the television demodulator AMF2 (audio output, weighted S/N ratio) better
than 60 dB (deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation
c) Picture-to-sound carrier ratio; pc/sc1 = 13 dB (transmitter).
20. The pc/sc1 ratio is calculated as the addition of TV transmitter pc/sc1 ratio and SAW filter pc/sc1 ratio. This pc/sc1
ratio is necessary to achieve the S/NW values as noted. A different pc/sc1 ratio will change these values.

22. Measurements taken with SAW filter G1962 (sound shelf: 20 dB) for vision and sound IF. Pin SIF1 and/or pin SIF2

SOLDERING
Introduction
Thistextgives a very brief insight toacomplextechnology.
A more in-depth account of soldering ICs can be found in
our
“Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-holeandsurfacemountcomponentsaremixedon
one printed-circuit board. Wave soldering can still be used
for certain surface mount ICs, but it is not suitable for fine
pitch SMDs. In these situations reflow soldering is
recommended.
Through-hole mount packages
SOLDERING BY DIPPING OR BY SOLDER WAVE
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joints 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.
MANUAL SOLDERING
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either 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.
Surface mount packages
REFLOW SOLDERING
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit board by screenprinting, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.

). If the
TDA9817; TDA9818
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.
WAVE SOLDERING
Conventional single wave soldering is not recommended
forsurfacemountdevices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
• Forpackageswithleads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
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.
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.
MANUAL SOLDERING
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron 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.

Suitability of IC packages for wave, reflow and dipping soldering methods
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the
2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
6. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
