Video control combination circuit with
TDA3507
automatic cut-off control
GENERAL DESCRIPTION
The TDA3507 is a monolithic integrated circuit which performs video control functions in a PAL/SECAM decoder.
The required input signals are: luminance and negative colour difference −(R−Y) and −(B−Y), and a 3-level sandcastle
pulse for control purposes. Linear RGB signals can be inserted from an external source. RGB output signals are available
for driving the video output stages. This circuit provides automatic cut-off control of the picture tube.
The TDA3507 is the same as the TDA3505 but with RGB channel bandwidths of (typical) 16 MHz and an automatic
cut-off cycle that ends in line 15.
Features
• Capacitive coupling of the colour difference and
luminance input signals with black level clamping in the
input stages
• Linear saturation control acting on the colour difference
signals
• (G−Y) and RGB matrix
• Linear transmission of inserted signals
• Equal black levels for inserted and matrixed signals
• 3 identical channels for the RGB signals
• Linear contrast and brightness controls, operating on
both the inserted and matrixed RGB signals
• Peak beam current limiting input
• Clamping, horizontal and vertical blanking of the three
input signals controlled by a 3-level sandcastle pulse
• 3 DC gain controls for the RGB output signals (white
point adjustment)
• Emitter-follower outputs for driving the RGB output
stages
• Input for automatic cut-off control with compensation for
leakage current of the picture tube

Notes
1. < 115 mA after warm-up.
2. Values are proportional to the supply voltage.
3. When V
< 0,4 V during clamping time the black levels of the inserted RGB signals are clamped on the black
11-24
levels of the internal RGB signals.
When V
> 0,9 V during clamping time the black levels of the inserted RGB signals are clamped on an internal
11-24
DC voltage (correct clamping of the external RGB signals is possible only when they are synchronous with the
sandcastle pulse).
4. When pins 21, 22 and 23 are not connected, an internal bias voltage of 5,5 V is supplied.
5. Automatic cut-off control measurement occurs in the following lines after start of the vertical blanking pulse:
line 12: measurement of leakage current (R + G+ B)
line 13: measurement of red cut-off current
line 14: measurement of green cut-off current
line 15: measurement of blue cut-off current
6. Black level of the measured channel is nominal; the other two channels are blanked to ultra-black.
7. All three channels blanked to ultra-black.
The cut-off control cycle occurs when the vertical blanking part of the sandcastle pulse contains more than 3 line
pulses.
The internal blanking continues until the end of the last measured line.
The vertical blanking pulse is not allowed to contain more than 34 line pulses, otherwise another control cycle begins.
8. The sandcastle pulse is compared with three internal thresholds (proportional to VP) and the given levels separate
the various pulses.

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.
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.
