Overview

The LC8213K compresses and expands the binary image data used in fax and similar applications and can be used in office automation equipment such as G3 or G4 facsimile systems, image filing systems, digital copiers, and engineering workstations. The LC8213K supports encoding methods that conform to the MH (Modified Huffman), MR (Modified relative element address designate), and MMR (Modified MR) encoding techniques as stipulated in the ITU-T T.4 and T.6 recommendations.
