W9954F

m o .c U 4 t e e h GENERAL DESCRIPTION S a atW9954F is a high performance digital The W9953F/ D which converts a 4:2:2 ITU-R 601/656 video encoder . digital video stream into a standard analog base w band composite video and Y/C video signals, which w compatible with worldwide standards. w The W9953F/ W9954F can operate in either master W9953F/W9954F TV ENCODER Master or slave operation modes Programmable sync polarity and horizontal phase Programmable Y/C delay relationship Sync extraction from digital input data Interlaced or non-interlaced operation Closed captioning and WSS/CGMS encoding PAL-WST Teletext encoding Fast I2C-bus control port or slave mode and interlaced or non-interlaced mode. The on-chip 2X over sampling eases the analog post-filtering. Three 10-bit resolution D/A converters provide Y,C and CVBS signals, all in standard video-level at doubly terminated 75 Ω loads. The chips provide Closed-Caption, WSS/ CGMS and teletext functions. The W9953F also provides Macrovision 7.01 copy protection, but W9954F doesn't provide this function. FEATURES Full multi-standard digital encoder supports NTSC-M, PAL-B, D, G, H, I, N and M encoding Accepts ITU-R 601/ 656 8-bit YCbCr (4:2:2) input format Three 10-bit DACs, run at 2X pixel rate, provide Y,C and CVBS outputs.
