NXP Semiconductors TDA3504
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.| Part No. | 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
● 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
