GENERAL DESCRIPTION
The SAA5284 is a Vertical Blanking Interval (VBI) and Full
Field (FF) video data acquisition device tailored for
application on PC add-in cards, PC mother-boards, set-top
boxes and as a SAA5250 replacement. The IC in
combination with a range of software modules will acquire
most existing formats of broadcast VBI and FF data.
These associated software modules are available under
licence. Scope is provided for acquiring some as yet
unspecified formats. The SAA5284 incorporates all the
data slicing, parallel interface, data filtering and control
logic. It is controlled either by a parallel interface or
I
2
C-bus. It can output ASCII VBI data as pixels on the
digital video bus where no parallel port is available. It is
available in a QFP44 package.
