GENERAL DESCRIPTION
The TDA3567 is a monolithic integrated decoder for the NTSC colour television standards. It combines all functions
required for the demodulation of NTSC signals. Further more it contains a luminance amplifier, an RGB-matrix and
amplifier. These amplifiers supply output signals up to 5 V peak-to-peak (picture information) enabling direct drive of the
discrete output stages.

FUNCTIONAL DESCRIPTION
Luminance amplifier
(1)
The luminance amplifier is voltage driven and requires an input signal of 450 mV peak-to-peak
line must be connected between the i.f. amplifier and the decoder. The input signal must be a.c. coupled to the input pin 8.
The black level clamp circuit of the RGB amplifiers uses the coupling capacitor as a storage capacitor. After clamping
the signal is fed to a peaking stage. The RC network connected to pin 13 is used to define the amount of overshoot.
The peaking stage is followed by a contrast control stage. The control voltage has to be supplied to pin 6. The control
voltage range is nominally −17 to + 3 dB. The linear curve of the contrast control voltage is shown in Fig.2.
Chrominance amplifier
The chrominance amplifier has an asymmetrical input. The input signal at pin 3 must be a.c. coupled, and must have an
amplitude of 550 mV peak-to-peak. The gain control stage has a control range in excess of 30 dB, the maximum input
signal should not exceed 1,1 V peak-to-peak, otherwise clipping of the input signal will occur. From the gain control stage
the chrominance signal is fed to the saturation and contrast control stages. Chrominance and luminance control stages
are directly coupled to obtain good tracking. The saturation is linearly controlled via pin 5. The control voltage range is
2 V to 4 V. The impedance is high and the saturation control range is in excess of 50 dB. The burst signal is not affected
by contrast or saturation control. After the amplification and control stages the chrominance signal is internally fed to the
(R-Y) and (B-Y) demodulators, burst phase and a.c.c. detectors.
The luminance delay
Oscillator and a.c.c. circuit
The 3,58 MHz reference oscillator operates at the subcarrier frequency. The crystal must be connected between pin 16
and ground. The oscillator does not require adjustment due to the small spreads of the IC. The free running frequency
of the oscillator can be checked by connecting the saturation control (pin 5) to the positive supply line. Then the loop is
opened, so that the frequency can be measured. The oscillator has an internal gain limiting stage which controls the gain
to unity, so that internal signals are sinusoidal. This prevents the generation of higher harmonics of the subcarrier signals.
The burst signal is compared to a 0° reference signal by the burst amplitude detector and is then amplified and fed to a
peak detector for a.c.c. and to a sample and hold circuit which drives the colour killer circuit. The reference signal for the
burst phase detector is provided by the 90° phase shifted signal. An RC network is used to obtain the required catching
range and noise immunity for the output voltage of the burst phase detector.
The hue control is obtained by mixing oscillator signals with a phase of 0° and 90° before they are fed to the (R-Y) and
(B-Y) demodulators. The 90°phase shifted signal is provided by a miller integrator (biased by pin 18). As the hue control
is independent of the PLL, the control will react without time delay on the control voltage changes.
Demodulator circuits
The demodulators are driven by the amplified and controlled chrominance signals, the reference signals are obtained
from the hue control circuit. In nominal hue control position the phase angle of (R-Y) reference signal is 0°, the phase
angle of the (B-Y) reference signal is 90°.
For flesh tone corrections the demodulated (R-Y) signal is matrixed with the demodulated (B-Y) signal according to the
following equations:

In these equations (R-Y)IN and (B-Y)IN indicate the colour difference signal amplitudes, when the chrominance signal is
demodulated with a phase difference between the R-Y and B-Y demodulator of 90° and a gain ratio B-Y/R-Y = 1,78.
RGB matrix circuit and amplifiers
The three matrix and amplifier circuits are identical. The luminance signal and the colour difference signals are added in
the matrix circuit to obtain the colour signal.
Output signals are 5 V (peak-to-peak) (black-white) for the following nominal input signals and control settings.
• Luminance 450 mV (peak-to-peak)
• Chrominance 550 mV (peak-to-peak) (burst-to-chrominance ratio of the input 1 : 2.2)
• Contrast −3 dB (maximum)
• Saturation −10 dB (maximum)
The maximum available output voltage is approximately 7 V (peak-to-peak). The black level of the red channel is
compared with a variable external reference level (pin 9), which provides the brightness control. The control loop is
closed via the luminance input.
The luminance input is varied to control the black level control, therefore the green and blue outputs will follow any
variation of the red output. The output of the black control can be varied between 2 V to 4 V. The corresponding
brightness control voltage is shown in Fig.4.
If the output signal surpasses the level of 9 V the peak-white limiter circuit becomes active and reduces the output signal
via the contrast control.
Blanking of RGB signals
A slicing level of about 1,5 V is used for this blanking function, so that the wide part of the sandcastle pulse is separated
from the rest of the pulse. During blanking a level of + 2 V is available at the output.

Notes to the characteristics
1. Signal with negative going sync; amplitude includes sync pulse amplitude.
2. Indicated is a signal for colour bar with 75% saturation, so the chrominance to burst ratio is 2,2 : 1.
3. Nominal contrast is specified as maximum contrast −3 dB and nominal saturation as maximum saturation −10 dB.
4. Cross coupling is measured under the following condition:
- input signals nominal;
- contrast and saturation such that nominal output signals are obtained;
- the signals at the output at which no signal should be available must be compared with the nominal output signal
at that output.
5. The signal-to-noise ratio is specified as peak-to-peak signal with respect to RMS noise.
6. When this level is exceeded the amplifier of the output signal is reduced via a discharge of the capacitor on pin 7
(contrast control). Discharge current is 5,5 mA.
7. These matrixed values are found by measuring the ratio of the various output signals. The values are derived from
the matrix equations given in the section ‘FUNCTIONAL DESCRIPTION’.

SOLDERING
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 situations 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 dipping or by 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 up to the seating plane, but the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
be necessary immediately after soldering to keep the temperature within the permissible limit.
(order code 9398 652 90011).
). If the printed-circuit board has been pre-heated, forced cooling may

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.
