Video control combination circuit with automatic cut-off control
GENERAL DESCRIPTION

TDA3507

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 QUICK REFERENCE DATA PARAMETER Supply voltage (pin 6) Supply current Composite video input signal (peak-to-peak value) Colour difference input signals (peak-to-peak value) -(B-Y) -(R-Y) Inserted RGB signals (black-to-white value) Three-level sandcastle pulse V12,13,14-24 V10-24 - - - - Control voltage ranges brightness contrast saturation PACKAGE OUTLINE 28-lead DIL; Plastic (SOT117); SOT117-1; 1996 November 21.

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 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. 9. Blanked to ultra-black (-25%). 10. Pulse duration 3,5 s.

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. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
