TDA9183

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 × fSC colour subcarrier signal may be

applied

• Alignment free

• Few external components

• Low power.

GENERAL 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.

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 colour

subcarrier 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 IC is available in a DIP16 and SO16 package.

The supply voltage is 5 V.
