TDA3504
Description
GO 19 RO 18 GND 17 BRI 16 CON TDA3504 15 14 (B Y) (R Y) 6 7 8 13 n.c. 12 SAT 11 Y MSA513 RI 10 Fig.2 Pin configuration. LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).
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
- 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 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. Linear RGB signals can be inserted from an external source. RGB output signals are available for driving the video output stages.
