FUNCTIONAL DESCRIPTION
Vision IF amplifier

The vision IF amplifier consists of three AC-coupled
differential amplifier stages. Each differential stage
comprises a feedback network controlled by emitter
degeneration.

Tuner and VIF AGC

The AGC capacitor voltage is transferred to an internal IF
control signal, and is fed to the tuner AGC to generate the
tuner AGC output current (pin TAGC, open-collector
output). The tuner AGC takeover point can be adjusted.
This allows the tuner and the SWIF filter to be matched to
achieve the optimum IF input level.

The AGC detector charges/discharges the AGC capacitor
to the required voltage for setting of VIF and tuner gain in
order to keep the video signal at a constant level.
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.

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 proportional to the
phase difference between the VCO and the input signal.
The DC current of either frequency detector or phase
detector is converted into a DC voltage via the loop filter,
which controls the VCO frequency. In the event of positive
modulated signals the phase detector is gated by
composite sync in order to avoid signal distortion for
overmodulated VIF signals. This mode can be switched off
by the L/L accent gating switch.

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 (PC) frequency.

TDA9810

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 PC
frequency is generated by the Frequency-Phase detector
and fed via the loop filter to the first variable capacitor
(FPLL). This control voltage is amplified and additionally
converted into a current which represents the AFC output
signal. 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/L accent
gating switch. In this event the second variable capacitor
can be controlled by a variable resistor at the L/L accent
gating switch for setting the VCO centre frequency to the
required L accent value. At centre frequency the AFC
output current is equal to zero.

The oscillator signal is divided-by-two 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 is 1 V (p-p)
for nominal vision IF modulation.

Video buffer

For an easy adaption of the sound traps an operational
amplifier with internal feedback is used in the event of B/G
and L standard. This amplifier is featured with a high
bandwidth and 7 dB gain. The input impedance is adapted
for operating in combination with ceramic sound traps.
The output stage delivers a nominal 2 V (p-p) positive
video signal. Noise clipping is provided.

SIF amplifier and 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 signals
(average level of AM or FM carriers) and controls the SIF
amplifier to provide a constant SIF signal to the AM
demodulator and single reference QSS mixer. 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 also set to ‘fast’
controlled by the standard switch.

Single reference QSS mixer

The single reference QSS mixer is 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 10. With this system a high performance hi-fi stereo
sound processing can be achieved.

TDA9810

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. This AM output signal can
be muted by using the AM mute switch.

Internal voltage stabilizer and

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.

For all audio output signals the constant reference voltage
cannot be used because large output signals are required.
Therefore these signals refer to half the supply voltage to
achieve a symmetrical headroom, especially for the
rail-to-rail output stage. For ripple and noise attenuation

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 application information for designing the
television receiver.

3. Loop bandwidth BL = 70 kHz (natural frequency fn= 12 kHz; damping factor d ≈ 3; calculated for peak level).

7. Offset current measured between pin 4 and half of supply voltage (VP= 2.5 V) under the following conditions: no
input signal at VIF input (pins 1 and 2) and VIF amplifier gain at minimum (V21=VP). Due to sample-and-hold mode
of the FPLL in L standard, the leakage current of the loop filter capacitor (C = 220 nF) should not exceed 500 nA.

8. Measurements taken with SAW filter K6257 (sound carrier suppression: 40 dB); loop bandwidth = 70 kHz.
a) Modulation VSB; sound carrier off; f
b) Sound carrier on; SIF SAW filter K9453; f

9. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typically 2 V (p-p), in event of
CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 Ω resistor must be connected from
output to input (from pin 9 to pin 13).

10. 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.

11. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 12). B = 5 MHz weighted

13. Response speed valid for a VIF input level range of 200 µVupto70mV.

14. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.8. The AFC-steepness can be changed by the resistors at pin 17.

depends on its AM modulation.

18. The V

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. Measurements taken with SAW filter K6257 (Siemens) for vision IF (suppressed sound carrier) and K9453
(Siemens) for sound IF (suppressed picture carrier). Input level V

i(SIF)(rms)

= 10 mV, 27 kHz (54% FM deviation).

21. The PC/SC ratio at pins 1 and 2 is calculated as the addition of TV transmitter PC/SC ratio and SAW filter PC/SC
ratio. This PC/SC ratio is necessary to achieve the S/NW values as noted. A different PC/SC ratio will change
these values.

22. Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier).

23. The input voltage has to be Vi> 2.8 V, or open-circuit.

SOLDERING DIP, SDIP, HDIP, DBS and SIL
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
cases 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”

Soldering by dip or wave

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 to the seating plane, but the
temperature of the plastic body must not exceed the
specified storage maximum. If the printed-circuit board has
been pre-heated, forced cooling may be necessary
immediately after soldering to keep the temperature within
the permissible limit.

Repairing soldered joints

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.

Reflow soldering

Reflow soldering techniques are suitable for all
SO packages.

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
between 50 and 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. Preheating duration: 45 minutes at
45 °C.

Wave soldering

Wave soldering techniques can be used for all
SO packages if the following conditions are observed:

• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.

• The longitudinal axis of the package footprint must be
parallel to the solder flow.

• The package footprint must incorporate solder thieves at
the downstream end.

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.

Repairing soldered joints

Fix the component by first soldering two
diagonally-opposite 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 at
between 270 and 320 °C.
