Employing adaptive filter technology, the AL240 video decoders are 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 colour effects.
Featuring fully programmable video characteristic controls (hue, contrast, brightness, saturation), the AL240 decoders incorporate advanced vertical blanking interval (VBI) data processors to do data slicing, parsing and decoding teletext, closed caption, and other formats. Two wires of hardware channel switching inputs allow decoders to do an instant alternation of analogue 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 Low Power Adaptive Comb Filter Video Decoders support power saving mode and operate under the low power voltages (3.3V and 1.8V) in 44-pin Lead Free (PBF) QFP package.
Some of the applications of these decoders include:
- Video Surveillance Systems
- Mobile Systems
- Hand-held Applications
- Video Capture Devices
- Video Phone
- Networking Video, etc.
