DVI-I Support
The RS780E has the capability of driving both digital and analog outputs simultaneously to a DVI-I connector. This is
accomplished by routing the RED, GREEN, BLUE, DACHSYNC, DACVSYNC, and AVSSN signals from the
RS780E's CRT output (see
C4(HS), C5(GND), and Pin 8 (VS) signals (see
For the DVI output portion of the DVI-I connector, AMD recommends using the RS780E's LVTM interface to provide
the DVI output and routing these digital signals (see
appropriate inputs on the DVI-I connector. The video BIOS must be configured so that the RS780E drives out DVI
signals from its LVTM interface. Display modes supported include desktop resolutions such as 800x600, 1024x768,
1152x864, 1280x1024, and 1600x1200 at 16bpp or 32bpp, with 60Hz or 75Hz screen refresh rate.

Clock Generation
The RS780E provides support for an external clock chip to generate side-port memory, PCI-E, and A-Link II clocks. For
information on the supported external clock chips, please consult your AMD CSS representative.
