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
(GY) and RGB matrix
Linear transmission of inserted signals
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.
GENERAL DESCRIPTION
The TDA3504 is an integrated circuit which performs video control functions in a PAL/SECAM decoder for negative colour difference signals (RY) and (BY).
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.
QUICK REFERENCE DATA
All voltages referenced to pin 18 (ground).
