Description

The LA7437, 7437A is a video signal processing singlechip C that handles the PAL-G, B and I, 4.43 NTSC, and ESECAM ormats. IC internal trimming is used to make he LA7437, 7437A is completely adjustment free, and in ombination ith a special-purpose CCD (the C89973M) it provides a significant reduction in external omponents, including the lass delay line. Thus the A7437, 7437A can significantly reduce the signal rocessing board manufacturing costs. rthermore, the A7437, 7437A supports the NAP format (NTSC to PAL onversion) that is poised to become idespread in urope, China and other markets.
