LF2272

The LF2272 is a high-speed digital colorspace converter/corrector consisting of three simultaneous 12-bit input and output channels for func- tionality up to 64 Giga (236 ) colors.

Some of the applications the LF2272 can be used for include phosphor colorimetry correction, image captur- ing and manipulation, composite color encoding/decoding, color matching,and composite color standards conversion/transcoding.

The 3 x 3 matrix multiplier (triple dot product) allows users to easily per- form three-dimensional perspective translations or video format conver- sions at real-time video rates.  By using the LF2272, conversions can be made from the RGB (color compo-nent) format to the YIQ (quadrature encoded chrominance) or YUV (color difference) formats and vice versa (YIQ or YUV to RGB).  Differing signal formats in each stage of a system can be disregarded.  For example, using an LF2272 at each format interface allows each stage of a system to operate on the data while in the appropriate format.

All inputs and outputs, as well as all control lines, are registered on the rising edge of clock.  The LF2272 operates at clock rates up to 50 MHz over the full commercial temperature and supply voltage ranges.  A nar- rower data path can be used to allow the LF2272 to work with many different imaging applications.
