NXP Semiconductors TDA3507
The TDA3507 is a monolithic integrated circuit which performs video control functions in a PAL/SECAM decoder. The required input signals are: luminance and negative colour difference −(R−Y) and −(B−Y), and a 3-level sandcastle pulse for control purposes. This circuit provides automatic cut-off control of the picture tube.| Part No. | TDA3507 |

GENERAL DESCRIPTION
TDA3507 Linear RGB signals can be inserted from an external source. RGB output signals are available for driving the video output stages. The TDA3507 is the same as the TDA3505 but with RGB channel bandwidths of (typical) 16 MHz and an automatic cut-off cycle that ends in line 15.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 QUICK REFERENCE DATA PARAMETER Supply voltage (pin 6) Supply current Composite video input signal (peak-to-peak value) Colour difference input signals (peak-to-peak value) −(B−Y) −(R−Y) Inserted RGB signals (black-to-white value) Three-level sandcastle pulse V12,13,14-24 V10-24 − − − − Control voltage ranges brightness contrast saturation PACKAGE OUTLINE 28-lead DIL; Plastic (SOT117); SOT117-1; 1996 November 21.
