Monolithic integrated 16 : 9 compressor

GENERAL DESCRIPTION The integrated 16 : 9 compressor is an IC which compresses the active part of a video line by a factor of 4⁄3 from, for example, 52 µs to 39 µs. This is necessary to display 4:3 video software on a 16 : 9 tube in the correct proportion. The capacitively coupled video inputs ar
