NXP Semiconductors TDA3505
The TDA3505 and TDA3506 are monolithic integrated circuits which perform video control functions in a PAL/SECAM decoder. The TDA3505 is for negative colour difference signals −(R-Y), −(B-Y) and the TDA3506 is for positive colour difference signals +(R-Y), +(B-Y). The required input signals are: luminance and colour difference (negative or positive) and a 3-level sandcastle pulse for control purposes.| Part No. | TDA3505 |

GENERAL DESCRIPTION
TDA3505 TDA3506 Linear RGB signals can be inserted from an external source. RGB output signals are available for driving the video output stages. The circuits provide automatic cut-off control of the picture tube.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) or +(B-Y) respectively −(R-Y) or +(R-Y) respectively 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 20.
