TDA3506
GENERAL DESCRIPTION
The TDA3505 and TDA3506 are monolithic integrated circuits which perform video control functions in a PAL/SECAM
decoder. The TDA3505 is for negative colour difference signals −(R-Y), −(B-Y) and the TDA3506 is for positive colour
difference signals +(R-Y), +(B-Y).
The required input signals are: luminance and colour difference (negative or positive) 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. The circuits provide automatic cut-off control of the picture tube.
• Linear contrast and brightness controls, operating on
Features
both the inserted and matrixed RGB signals
• Capacitive coupling of the colour difference and
luminance input signals with black level clamping in the
input stages
• Peak beam current limiting input
• Clamping, horizontal and vertical blanking of the three
input signals controlled by a 3-level sandcastle pulse
• Linear saturation control acting on the colour difference
signals
• 3 DC gain controls for the RGB output signals (white
point adjustment)
• (G-Y) and RGB matrix
• Emitter-follower outputs for driving the RGB output
stages
• Linear transmission of inserted signals
• Equal black levels for inserted and matrixed signals
• 3 identical channels for the RGB signals
• Input for automatic cut-off control with compensation for
leakage current of the picture tube

Notes
1. < 110 mA after warm-up.
2. Values are proportional to the supply voltage.
3. When V11-24 < 0,4 V during clamping time - the black levels of the inserted RGB signals are clamped on the black
levels of the internal RGB signals.
When V11-24 > 0,9 V during clamping time - the black levels of the inserted RGB signals are clamped on an internal
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 20: measurement of leakage current (R + G + B)
line 21: measurement of red cut-off current
line 22: measurement of green cut-off current
line 23: 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.
9. Blanked to ultra-black (−25%).
10. Pulse duration ≥ 3,5 µs.

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” (order code 9398 652 90011).
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 (Tstg max). 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.
