Modulation (DPCM) input colour formats; 4 : 1 : 1 and
4 : 2 : 2 output colour formats
• Full 8-bit accuracy
• Scalable performance by applying 1, 2 or 3 external
field memories
• Improved recursive de-interlacing
• Film (25 Hz, 30 Hz) upconversion to 100/120
movement phases per second

• 2 Mbaud serial interface (SNERT).
2 GENERAL DESCRIPTION
The SAA4992H 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’ performance and full
film upconversion for all 50 and 60 Hz film material.
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 a colour vector overlay is available.
The SAA4992H supports a Boundary Scan Test (BST)
circuit in accordance with IEEE 1149.
