AL260C-EVB-A4 Main Board with AL240/242 Daughter Board (EOL)



AL260 is an highly integrated Video Enhancement Processor that supports video input with multiple video formats and video output with De-interlacing and Scaling effects .It can be used for most video conversion and processing applications.

Al260 is equipped with a high quality scaling engine that automatically maintains
full screen output display, regardless of resolution of the incoming signals. Applying AverLogic’s proprietary scaling algorithm, the primary input video can be scaled up and scaled down independently in horizontal and vertical directions. It also provides film detection, advanced motion adaptive de-interlacing, filtering, and scaling functions that are able to convert and process the interlaced video to be displayed on progressive panels.

AL260 has a built-in 3-channel DAC for non-interlaced analog output. It also supports
24-bit digital progressive- scan output. It is equipped with a 208-pin PQFP package.
