® SDVO Modes

The port can be dynamically configured in several modes:

• Standard. This mode provides baseline SDVO functionality. Supports Pixel Rates between

25 and 200 MP/s. Utilizes three data pairs to transfer RGB data.

• Extended. This mode adds Alpha support to data stream. Extended mode supports Pixel rates

between 25 MP/s and 200 MP/s. The mode uses four data channels and is only supported on

SDVOB. Leverages channel C (SDVOC) Red pair as the Alpha pair for channel B (SDVOB).

Note: Operating in extended SDVO mode is mutually exclusive to the use of a second display

on SDVO.

• Dual Standard. This mode uses Standard data streams across both SDVOB and SDVOC.

Both channels can only run in Standard mode (3 data pairs) and each channel supports Pixel

Rates between 25 and 200 MP/s.

⎯ Dual Independent Standard (82915G only). In Dual Independent Standard mode, each

SDVO channel will see a different pixel stream. The data stream across SDVOB will not

be the same as the data stream across SDVOC.

⎯ Dual Simultaneous Standard. In Dual Simultaneous Standard mode, both SDVO

channels will see the same pixel stream. The data stream across SDVOB will be the same

as the data stream across SDVOC. The display timings will be identical, but the transfer

timings may not be (i.e., SDVOB clocks and data may not be perfectly aligned with

SDVOC clock and data as seen at the SDVO device(s)). Since this mode uses just a

single data stream, it uses a single pixel pipeline within the GMCH.
