TDA3505 Overview
TDA3505 TDA3506 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:.
TDA3505 Key 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 posite vid
