AL240 General Description

The AL240 is silicon efficient, cost effective high video quality NTSC/PAL SECAM video decoder with high quality Y/C separation process. The AL240 decodes NTSC/PAL/SECAM composite video or S-video and convert it into YCbCr 4:2:2, 8-bit digital video output. Employing adaptive filter technology, the AL240 is able to provide a clear Y/C separated signals while maintaining excellent frequency response. The result is sharp, high detail video that eliminates unwanted dot crawl and false color effects. Fully programmable video characteristic controls, such as hue, contrast, brightness, saturation, are supported. The AL240 decoder incorporates an advanced vertical blanking interval (VBI) data processor to do data slicing, parsing and decoding teletext, closed caption, and other formats. Two wires of hardware channel switching inputs allow decoder to do an instant alternation of analog CVBS inputs from one to the other. Up to 4 serial bus addresses can be selected via two configuration pins that allow multiple AL240 chips on the design without extra logic.

The AL240 supports power saving mode and operates under the low power voltages (3.3V and 1.8V) in 44-pin Lead Free (PBF) QFP package.
