16.9.1.
General Features:
-One chip multistandart adaptive comb filter
-Cross luminance reduction
-Cross colour reduction
-No chroma trap, so sharper vertical luminance
-Analogue discrete-time signal processing, so 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
