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
