Description

The MC44724A and MC44725A are advanced Digital Video Encoders (DVE). They convert ITU-601/656 standard 4:2:2 Bit- Paralellel data into analog composite video, S-Video or analog component signals Y/Cb/Cr or R/G/B in PAL and NTSC formats. MC44724A and MC44725A accept the multiplexed two 8-bit or 16-bit ((CB,Y,CR)Y) signals from digital sources such as MPEG decoders and can act as a sync generator master or as a sync slave. All video processing is done digitally and requires no external adjustment.

MC44724A and MC44725A are specifically designed for digital satellite, digital cable decoders, multimedia terminals and DVD players.
