Product specification
Video control combination circuit with
automatic cut-off control
TDA3508
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
• Three identical channels for the RGB signals
• Linear contrast and brightness controls, operating on
both the inserted and matrixed RGB signals
• Peak beam current limiting input
• Clamping, horizontal and vertical blanking of the three
input signals controlled by a 3-level sandcastle pulse
• Three DC gain controls for the RGB output signals
(white point adjustment)
• Emitter-follower outputs for driving the RGB output
stages
• Input for automatic cut-off control with compensation for
leakage current of the picture tube.
GENERAL DESCRIPTION
The TDA3508 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. The circuit provides
automatic cut-off control of the picture tube.
