TDA9812

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 (open-collector output). The
tuner AGC take-over 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 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.

VCO, travelling wave divider and AFC

The VCO operates with a resonance circuit (with L and C
in parallel) at double the PC frequency. The VCO is
controlled by two integrated variable capacitors. The
control voltage required to tune the VCO from its free­running 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/L accent standard) by activating an additional internal
capacitor. This is achieved by using the L/L accent switch.
In this event the second variable capacitor can be
controlled by a variable resistor at the L/L accent switch for
setting the VCO centre frequency to the required
L/L accent value. At centre frequency the AFC output
current is equal to zero.

The oscillator signal is divided-by-two with a Travelling
Wave Divider (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 for AM sound

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 carrier) and controls the SIF amplifier
to provide a constant SIF signal to the AM demodulator.
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.

Intercarrier mixer

The intercarrier mixer is realized by a multiplier. The VIF
amplifier output signal is fed to the intercarrier 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.

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.

FM detector

The FM detector consists of a limiter, an FM-PLL and an
AF amplifier. The limiter provides the amplification and
limitation of the FM sound intercarrier signal before
demodulation. 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
and to save pins for DC decoupling.

The FM-PLL consists of an integrated 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

The AF amplifier consists of two parts:

• The AF preamplifier 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
characteristic of the amplifier reduces the harmonics of
the intercarrier signal at the sound output terminal, at
which the de-emphasis network for FM sound is applied.
An additional DC control circuit is implemented to keep
the DC level constant, independent of process spread.

• The AF output amplifier (10 dB) provides the required
output level by a rail-to-rail output stage. 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 and

1

⁄2VP-reference

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
the

1

⁄2VP voltage has to be filtered via a low-pass filter by

using an external capacitor together with an integrated
resistor (fg= 5 Hz). For a fast setting to 1⁄2VP an internal
start-up circuit is added.

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 = 60 kHz (natural frequency fn= 15 kHz; damping factor d = 2; calculated with sync level within
gain control range). Resonance circuit of VCO: Q0> 50; C

ext

= 8.2 pF ±0.25 pF; C

int

≈ 8.5 pF (loop voltage

approximately 2.7 V).

4. Temperature coefficient of external LC-circuit is equal to zero.

5. V

7. Offset current measured between pin 7 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 (V28=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 G1962 (sound shelf: 20 dB); loop bandwidth BL = 60 kHz.
a) Modulation VSB; sound carrier OFF; f

video

> 0.5 MHz.

b) Sound carrier ON; SIF SAW filter L9453; f

video

= 10 kHz to 10 MHz.

9. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typical 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 21 to pin 22).

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 10). 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.12. The AFC-steepness can be changed by the resistors at pin 23.

15. Depending on the ratio ∆C/C0 of the LC resonant circuit of VCO (Q > 50; see note 3; C0=C

).

16. Source impedance: 2.3 kΩ in parallel to 12 pF (SAW filter); f

IF

= 38.9 MHz.

17. The intercarrier output signal at pin 20 can be calculated by the following formula taking into account the video output
signal at pin 21 (V

o video(p-p)

= 1 V typical) as a reference:

with = correction term for RMS value,

= sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB,

6 dB = correction term of internal circuitry
and ±3 dB = tolerance of video output and intercarrier output amplitude V

o(rms)

.

Example: SAW filter G1962 (sound shelf: 20 dB) ⇒⇒ V

o(rms)

= 32 mV typical.

18. Input level for second IF from an external generator with 50 Ω source impedance. AC-coupled with 10 nF capacitor,
f

mod

= 1 kHz, 27 kHz (54% FM deviation) of audio references. A VIF/SIF input signal is not permitted. Pins 8 and 28
have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 µs
de-emphasis.
Second IF input level 10 mV RMS.

19. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV RMS (Rx=0Ω; see Fig.17). By
using Rx= 470 Ω the AF output signal is attenuated by 6 dB (250 mV RMS). For handling an FM 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.

20. The leakage current of the decoupling capacitor (2.2 µF) should not exceed 1 µA.

21. For all S/N measurements the used vision IF modulator has to meet the following specifications:
Incidental phase modulation for black-to-white jump less than 0.5 degrees.
Picture-to-sound carrier ratio; PC/SC = 13 dB; (transmitter).
Sound shelf of VIF SAW filter: minimum 20 dB.

22. Measurements taken with SAW filter K6256 (Siemens) for vision and sound IF (sound shelf: 20 dB). Input level
V

i SIF

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

23. 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/N(W) values as noted. A different PC/SC ratio will change these
values.

24. Measurements taken with SAW filter L9453 (Siemens) for AM sound IF (suppressed picture carrier).

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

SOLDERING
Plastic dual in-line packages

B

Y DIP OR WAVE

The maximum permissible temperature of the solder is
260 °C; this temperature must not be in contact with the
joint for more than 5 s. The total contact time of successive
solder waves must not exceed 5 s.

The device may be mounted up 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.

R

EPAIRING SOLDERED JOINTS

Apply a low voltage soldering iron below the seating plane
(or not more than 2 mm above it). If its temperature is
below 300 °C, it must not be in contact for more than 10 s;
if between 300 and 400 °C, for not more than 5 s.

Plastic small outline packages

B

YWAVE

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.

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.

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.

B

Y 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.

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.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 min at 45 °C.

R

EPAIRING 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.)

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.
