TDA3506

INTEGRATED CIRCUITS DATA SHEET TDA3505 TDA3506 Video control combination circuit with automatic cut-off control Product specification File under Integrated Circuits, IC02 November 1987 Philips Semiconductors Product specification Video control combination circuit with automatic cut-off control GENERAL DESCRIPTION TDA3505 TDA3506 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. 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) or +(B-Y) respectively...
