Display
•
Analog display support
— 350-MHz integrated 24-bit RAMDAC that can drive a standard progressive scan analog
monitor with pixel resolution up to 1600x1200 at 85 Hz and up to 2048x1536 at 75 Hz
• Dual independent pipe support
— Concurrent: different images and display timings on each display device
— Simultaneous: same images and display timings on each display device
• DVO (DVOB and DVOC) support
— Digital video out ports DVOB and DVOC with 165-MHz dot clock on each 12-bit
interface; two 12-bit channels can be combined to form one dual channel 24-bit interface
with an effective dot clock of 330 MHz
— The combined DVO B/C ports as well as individual DVO B/C ports can drive a variety of
DVO devices (TV-Out Encoders, TMDS and LVDS transmitters, and so on) with pixel
resolution up to 1600x1200 at 85 Hz and up to 2048x1536 at 72 Hz.
