TDA9181 Overview
TDA9181 The TDA9181 is a an adaptive PAL/NTSC b filter with two internal delay lines, filters, clock control and input clamps. Video standards PAL B, G, H, D, I, M and N and NTSC M are supported. Two CVBS input signals can be selected by means of an input switch.
TDA9181 Key Features
- One-chip multistandard adaptive b filter
- Cross luminance reduction
- Cross colour reduction
- No chroma trap, therefore sharper vertical luminance transients
- Analog discrete-time signal processing, therefore no quantization noise
- Anti-aliasing and reconstruction filters are included
- Input switch selects between two Y/CVBS inputs
- Output switch selects between bed CVBS and an external Y/C source
- fSC as well as 2 × fSC colour subcarrier signal may be applied
- Alignment free
