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.

FEATURES

• Upconversion of all 1fH film and video standards up to 292 active input lines per field

• 100/120 Hz 2 : 1, 50/60 Hz 1 : 1 and 100/120 Hz 1 : 1 output formats

• 4 : 1 : 1, 4 : 2 : 2 and 4 : 2 : 2 Differential Pulse Code Modulation (DPCM) input colour formats; 4 : 1 : 1 and 4 : 2 : 2 output colour formats

• Full 8-bit accuracy

• Improved recursive de-interlacing

• Film (25 and 30 Hz) upconversion to 100/120 movement phases per second

• Variable vertical sharpness enhancement

• Motion compensated 3D dynamic noise reduction

• High quality vertical zoom

• 2 Mbaud serial interface (SNERT)

• Software and pin-to-pin compatible to SAA4992H (uses 3.3 V power supply) and SAA4993H

• Demonstration mode for noise reduction, motion compensation and colour overlay.
