File name Tda4580.pdf INTEGRATED CIRCUITS DATA SHEET TDA4580 Video control combination circuit with automatic cut-off control Product specification File under Integrated Circuits, IC02 March 1991 Philips Semiconductors Product specification Video control combination circuit with automatic cut-off control GENERAL DESCRIPTION The TDA4580 is a monolithic integrated circuit which performs video control functions in television receivers with a colour difference interface. For example it operates in conjunction the multistandard colour decoder TDA4555. The required input signals are: luminance and negative colour difference -(R-Y) and -(B-Y), and a 3-level sandcastle pulse for control purposes. Analogue RGB signals can be inserted from two sources. One with full performance adjustment possibilities. RGB output signals are available for driving the video output stages. This circuit provides automatic cut-off control of the picture tube. Features · Capacitive coupling of the colour difference, luminance and RGB input signals with black level clamping · Two sets of analogue RGB inputs via fast switch 1 and fast switch 2 · First RGB inputs and fast switch 1 in accordance with peritelevision connector specification · Saturation, contrast and brightness control acting on first RGB inputs TDA4580 · Brightness control acting on second RGB inputs · Equal black levels for television and inserted signals · Clamping, horizontal and vertical blanking, and timing of automatic cut-off, controlled by a 3-level sandcastle pulse · Automatic cut-off control with compensation for leakage current of the picture tube · Measuring pulses of cut-off control start immediately after end of vertical part of sandcastle pulse · Three selectable blanking intervals for PAL, SECAM and NTSC/PAL-M · Two switch-on delays for run-in without discolouration · Adjustable peak drive limiter · Average beam current limiter · G-Y and RGB matrix coefficients selectable for PAL/SECAM and NTSC (correction for FCC primaries) · Bandwidth 10 MHz (typ.) · Emitter-follower outputs for driving the RGB output stages QUICK REFERENCE DATA Supply voltage (pin 6) Supply current (pin 6) Luminance input (pin 15) Composite video input signal (VBS) (peak-to-peak value) Colour difference input signals (peak-to-peak values) -(B-Y) -(R-Y) Inserted RGB signals (black to white values) Inserted RGB signals for teletext use (black to white values) Three-level sandcastle pulse (required input voltage) PACKAGE OUTLINE 28-lead DIL; plastic (SOT117); SOT117-1; 1996 November 28.
