ML6440CH中文资料MICRO-LINEAR数据手册PDF规格书

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.

FEATURES

■ 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
