Video control combination circuit TDA3504

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

GENERAL DESCRIPTION

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).

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.

• 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.
