The two video pipelines are driven by two standard D1 interfaces, which can operate in various
modes in 8 or 10-bit precision. The following tables summarize the different modes of operation
for the video interface of the PNX8510/11.
The video interfaces and the sync raster engines are designed in a generic way. The only
limiting factor is the data rate of the received video streams. All formats with a total interface
speed requirement below 81 MHz can be displayed by the PNX8510/11.
