Micro Linear ML6440

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.

GENERAL DESCRIPTION

Internal filters with integrated adaption and compensation circuits provide filtered outputs with optimal video bandwidth and resolution while suppressing cross-color (rainbow), crossluminance (dot crawl) and other corrupting artifacts that can reduce video compression efficiency.

FEATURES

s SmartComb algorithm for automatic or manual selection adaption thresholds 3-line comb with 60+ line frame adjust Comb/notch thresholds set dynamically over 60+ lines automatically 12-bit processing minimizes truncation errors and maintains signal-to-noise performance Optional 8-bit composite or separated Y/C digital inputs

APPLICATIONS

: digital TV, line doubler, imaging Separate comb/notch filter thresholds for Luma and Chroma channels Optional pin controls or two-wire serial control interface Operating power dissipation less than 700mW No external components, except diode and caps s s s s s s s s s BLOCK DIAGRAM 18 19 20 21 22 23 24 25 * This Part Is End Of Life As Of August 1,...
