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 SAA5284 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 I2C-bus. SAA5284 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.
