·
·
·
·
·
·
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
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 W
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.
