TDA9183

GENERAL DESCRIPTION
  The TDA9183 is a an adaptive NTSC comb filter with twointernal 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 subcarrier frequency as well as twice the coloursubcarrier frequency may be applied to the IC. In addition to the comb filter the circuit contains an output switch so that a selection can be made between the combed CVBS signal and an external Y/C signal. The TDA9183 is available in a DIP16 and SO16 package. The supply voltage is 5 V.
