Product data
RGB 4:4:4
This mode is only useful if the HD data path in the PNX8510/11 is in operation. The
RGB 4:4:4 interface mode is not applicable to the standard definition RGB path
operation due to the implicit clocking requirements. The data rate for standard
definition RGB 4:4:4 data would be 13.5 MHz per component resulting in an interface
speed of 40.5 MHz. Because the chip does not contain any PLLs, it is not possible to
extract 27 MHz out of the interface clock.
YUV 4:4:4
This mode is useful only if the HD data path in the PNX8510/11 is in operation.
YUV 4:2:2 Interleaved
This mode supports two video data streams through one physical video interface. It
can be used to utilize both video encoder channels in the chip with one interface only
or to hook up two PNX8510/11 devices to one source providing an interleaved data
stream. Each chip extracts one slice from the interleaved stream. This video format is
useful for the encoder standard definition data path only.
