GENERAL DESCRIPTION
The W9953F/ W9954F is a high performance digital
video encoder which converts a 4:2:2 ITU-R 601/656
digital video stream into a standard analog base
band composite video and Y/C video signals, which
compatible with worldwide standards.
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
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
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

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.
FUNCTIONAL BLOCK
Note,
The difference between W9953F and W9954F is W9953F
provides Macro -vision 7.01 copy protection, but W9954F
doesn't provide this function.
The W9953F may be purchased by Macrovision Authorized
Buyers only.
