GENERAL DESCRIPTION
The SAA4994H is a completely digital monolithic
integrated circuit which can be used for field and line rate
conversion of all global TV standards.
It features improved Natural Motion
(1)
performance.
It can be configured to emulate the SAA4990H as well as
the SAA4991WP. For demonstration purposes a split
screen mode to show the Dynamic Noise Reduction
(DNR) function and natural motion is available and a
colour vector overlay mode exists.
The SAA4994H supports a Boundary Scan Test (BST)
circuit in accordance with IEEE 1149.
