INTEGRATED CIRCUITS DATA SHEET TDA3504 Video control combination circuit Product specification Supersedes data of April 1995 File under Integrated Circuits, IC02 1996 Jan 09 Philips Semiconductors Product specification Video control combination circuit TDA3504 FEATURES GENERAL DESCRIPTION * Capacitive coupling of the colour difference and luminance input signals with black level clamping in the input stages The TDA3504 is an integrated circuit which performs video control functions in a PAL/SECAM decoder for negative colour difference signals -(R-Y) and -(B-Y). * Linear saturation control acting on the colour difference signals The required input signals are luminance and colour difference 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. * (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 * Clamping, horizontal and vertical blanking of the three input signals controlled by a 3-level sandcastle pulse * Emitter-follower outputs for driving the RGB output stages.

Clipping due to internal signal limitation may occur when the Y input is greater than nominal and maximum contrast and minimum brightness. 5. When V7-18 < 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 V7-18 > 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). 6. Internal signal limitation is allowed to start at 5.5 V after warm-up time. 7. The sandcastle pulse is compared with three internal thresholds (proportional to VP) and the given levels separate the various pulses. 8. Blanked to ultra-black (-25%). 9.

The total contact time of successive solder waves must not exceed 5 seconds. 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. 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 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). 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. 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 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
