MC44724A数据手册恩XP中文资料规格书

描述 Description

Overview Convert ITU-601/656 standard 4:2:2 Bit-Parallel data into analog composite video,S-Video or Y/Cb/Cr or R/G/B in PAL and NTSC formats. The MC44724A and MC44725A are Digital Video Encoders (DVE). They convert ITU-601/656 standard 4:2:2 Bit-Parallel data into analog composite video, S-Video or Y/Cb/Cr or R/G/B in PAL and NTSC formats. They accept the multiplexed ((CB,Y, CR)Y) signals from digital sources such as MPEG® decoders and can act as a sync generator master. All video processing is done digitally and requires no external adjustment. Specifically designed for digital satellite, digital cable decoders and multimedia terminal.
