Features, Applications

The MC44722 and MC44723 are Digital Video Encoders (DVE). They convert ITU-601/656 standard 4:2:2 Bit-Paralellel data into analog composite video, S-Video or Y/Cb/Cr 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 terminals.

World Wide Operation (PAL-BDGHI, PAL-N,PAL-M, NTSC-M) SMPTE 170M / ITU R 624 composite video output Programmable Color Sub-carrier Frequencies Analog Horizontal, Vertical, Frame or Composite Sync Outputs Sync Extraction From Digital Input Data (SAV, EAV) Sync Polarity and Horizontal Phase Control Master or Slave Sync (H/Vsync, H/Fsync, ITU-R656 slave) Operation Interlaced or Non-Interlaced Support ITU-601/656 8-bit ((CB,Y,CR)Y) Digital Input Luma 2X / Chroma 4X Oversampling Filtering External VBI Information Data Input (such as TeleText Information Data) CVBS / Cr Analog Outputs Through 10-bit DACs Easily programmed via Serial Bus I2C or SPI Bus) 2 Hardware I2C Chip Addresses Closed-Caption and CGMS Information data Insertion MACROVISION ver. 7.01 Anti-Copy Signal Insertion (MC44722 Only support NTSC mode) On Chip Color - bar Generator +3.3V Power Supply or +3.3V(Digital)/+5V(Analog) Power Supply Pin Compatible with MC44720FT
