TDA9183 - Integrated NTSC comb filter

Description

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.

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.
