TDA9183 Product details

Description

TDA9183 The TDA9183 is a an adaptive NTSC comb filter with two internal delay lines, filters, clock control and input clamps.The NTSC M video standard is supported.Two CVBS input signals can be selected by means of an input switch.The selected CVBS input signal is filtered to obtain a combed luminance output signal and a combed chrominance output signal.Switched capacitor circuit techniques are used, requiring an internal clock, locked on to the colour subcarrier frequency.The colour subc

Features

One-chip NTSC adaptive comb 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 combed CVBS and an external Y/C source.
fSC as well as 2 × f.
