Multi-Standard 8-bit Adaptive Digital Input Comb Filter
GENERAL DESCRIPTION
The ML6440 SmartComb™ is a single-chip, 8-bit digital
comb filter that incorporates line delays and adaption
algorithms for NTSC and PAL at both CCIR601 and square
pixel rates. The ML6440 implements bandsplit filters and
a proprietary adaption and decision logic block that
allows for optimum combing over a wide range of video
sources.
The ML6440 contains all the necessary circuitry to provide
high quality combed output of luminance and
chrominance in the Y/C format. Internal filters with
integrated adaption and compensation circuits provide
filtered outputs with optimal video bandwidth and
resolution while suppressing cross-color (rainbow), cross-
luminance (dot crawl) and other corrupting artifacts that
can reduce video compression efficiency.
FEATURES
s SmartComb algorithm for automatic or manual
selection adaption thresholds
s 3-line comb with 60+ line frame adjust
s Comb/notch thresholds set dynamically over 60+ lines
automatically
s 12-bit processing minimizes truncation errors and
maintains signal-to-noise performance
s Optional 8-bit composite or separated Y/C digital inputs
s Applications: digital TV, line doubler, imaging
s Separate comb/notch filter thresholds for Luma and
Chroma channels
s Optional pin controls or two-wire serial control
interface
s Operating power dissipation less than 700mW
s No external components, except diode and caps
