heet4U.comGENERAL DESCRIPTION
ataSThe W9953F/ W9954F is a high performance digital
.Dvideo encoder which converts a 4:2:2 ITU-R 601/656
digital video stream into a standard analog base
wband composite video and Y/C video signals, which
wwcompatible with worldwide standards.
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
The W9953F/ W9954F can operate in either master
or slave mode and interlaced or non-interlaced
mode. The on-chip 2X over sampling eases the
manalog post-filtering. Three 10-bit resolution D/A
converters provide Y,C and CVBS signals, all in
ostandard video-level at doubly terminated 75 Ω
.cloads.
The chips provide Closed-Caption, WSS/ CGMS
and teletext functions.
UThe W9953F also provides Macrovision 7.01 copy
t4protection, but W9954F doesn't provide this function.
eFEATURES
e• Full multi-standard digital encoder supports
hNTSC-M, PAL-B, D, G, H, I, N and M encoding
• Accepts ITU-R 601/ 656 8-bit YCbCr (4:2:2) input
Sformat
ta• Three 10-bit DACs, run at 2X pixel rate, provide
Y,C and CVBS outputs.
• PAL-WST Teletext encoding
• Fast I2C-bus control port
• Macrovision Rev 7.01 copy protection process
(W9953F only)
• On chip color-bar generator
• Internal voltage reference
• Power down mode
• Monolithic CMOS 3.3V (5V) device
• 44-pin QFP package
APPLICATIONS
W9953F/ W9954F is designed for digital video
applications, such as DVD (Digital Versatile Disc),
players STBs (Set-Top Box), Multimedia PCs and
other video equipment.
