Proprietary
RS780E Features
•
YCbCr 4:4:4 and 4:2:2 support.
•
HDCP support
•
Optional test pattern support.
•
Supports two independent displays over the PCI-E interface for external graphics (see
Figure 1-1,“Possible
Configurations for the x16 PCI-E Graphics Interface,” on page 1-3
for details).
•
Supports 4, 2, or 1-lane transmission.
•
Supports both the 2.7Gbps and 1.62Gbps link symbol rates.
•
Supports the Auxiliary Channel (AUX CH).
•
Supports a maximum resolution of 2560x1600 @60Hz with 4 lanes.
1.2.13 Integrated HD Audio Controller and Codec
•
Integrated HD Audio codec supports linear PCM and AC3 (5.1) audio formats for HDMI output.
•
Separate logical chip function.
•
Can encrypt data onto one associated HDMI output.
•
Uses Microsoft UAA driver.
•
Internally connected to the integrated HDMI, or HDMI-enabled interface, hence no external cable required.
•
Support for basic audio (32, 44.1 or 48 KHz stereo) and AC3 or DTS at the same sample rates.
1.2.14 Clock Generation
•
Support for an external clock chip to generate side-port memory, PCI-E, and A-Link Express II clocks.
1.2.15 Power Management Features
•
Single chip solution in 55nm, 1.1V CMOS technology.
•
Supports ACPI 2.0 for S0, S3, S4, and S5 states.
•
Full IAPC (Instantly Available PC) power management support.
•
Static and dynamic power management support (APM as well as ACPI) with full VESA DPM and Energy Star
compliance.
•
The Chip Power Management Support logic supports four device power states defined for the OnNow Architecture—
On, Standby, Suspend, and Off. Each power state can be achieved by software control bits.
•
Hardware controlled intelligent clock gating enables clocks only to active functional blocks, and is completely
transparent to software.
•
Dynamic self-refresh for the side-port memory.
•
Support for Cool'n'Quiet™ via FID/VID change.
•
Support for AMD PowerNow!™.
•
Clocks to every major functional block are controlled by a unique dynamic clock switching technique that is
completely transparent to the software. By turning off the clock to the block that is idle or not used at that point, the
power consumption is significantly reduced during normal operation.
•
Supports PowerExpress™ and PowerPlay™ (enhanced with the PowerShift™ feature).
•
Supports dynamic lane reduction for the PCI-E graphics interface when coupled with an AMD-based graphics
device, adjusting lane width according to required bandwidth.
1.2.16 PC Design Guide Compliance
The RS780E complies with all relevant Windows Logo Program (WLP) requirements from Microsoft for WHQL
certification.
