This document introduces the datasheet of PHILIPS SAA4993H. This product is a field and line rate converter that supports 1fH film and video standards and provides 100/120Hz 2 : 1, 50/60 Hz 1 : 1 and 100/120 Hz 1 : 1 output formats.
The Philips SAA4993H is a completely digital monolithic integrated circuit designed for field and line rate conversion of all global TV standards. It features improved Natural Motion performance and supports upconversion of 1f, film, and video standards up to 292 active input lines per field.
The device can be configured to emulate the SAA4990H as well as the SAA4991WP. Key capabilities include 4:1:1 and 4:2:2 Differential Pulse Code Modulation (DPCM) input colour formats, full 8-bit accuracy, scalable performance via external field memories, improved recursive de-interlacing, film upconversion to 100/120 movement phases per second, variable vertical sharpness enhancement, motion compensated 3D dynamic noise reduction, and high quality vertical zoom.
