Philips Semiconductors
Integrated multistandard comb filter
Objective specification
TDA9181
FEATURES
One-chip multistandard 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 TDA9181 is a an adaptive PAL/NTSC comb 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.
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.
