Molex’s Advanced Digital Display 2 (ADD2) adapter

cards provide a convenient and cost-effective solution

for connecting a DVI digital display to the graphics

controller of any 915G or 946G-equipped motherboard

or high-end PC with a vacant PCI Express (PCIe) 16X

slot port. Simply insert the ADD2 card into the PCIe slot

and it will be DVI compatible. When the computer

boots-up, the system automatically loads the ADD2

card configuration information, which is stored in a

serial EEPROM.

ADD2 cards are small-size boards that ensure full

hardware and software compatibility, supporting the

full-range of digital display resolutions from VGA

(Video Graphics Array) to UXGA (Ultra Extended

Graphics Array). VGA is the standard for PCs,

providing a resolution of 720-by-400 pixels, while

UXGA is capable of displaying 1600-by-1200 pixel

resolution. Digital projectors, flat panel displays and

digital CRTs are all compatible with the ADD2 cards.

Intel’s 915G-based desktop accepts the ADD2-N (Non-

lane-reversed ) for ATX systems or ADD2-R (Lane-

reversed ) for BTX systems. The 945G-based desktop

accepts either card in either system (ATX or BTX). The

ADD2-N and ADD2-R cards are available with a

standard or low-profile PCIe bracket. ATX and BTX are

chassis form-factors introduced by Intel. Both cards

mate with MicroCross DVI-D receptacles.

Molex offers an extensive line of DVI cable assemblies.

Available in custom lengths and configurations,

virtually any cable requirement can be achieved.
