GENERAL DESCRIPTION
The SAA6721E is a graphics engine, which converts digital RGB or YUV data into video signals suitable for TFT displays. It supports SXGA input resolution as well as true colour. Independent horizontal and vertical up and downscaling can display the input data arbitrarily on the connected TFT display. Multi-sync capability allows the applied graphics mode to be detected.

Overlay signals can be generated either by an internal OSD generator or supplied via the overlay port from an external OSD controller.
