EDT designs and manufactures boards for a variety of bus specifications and form factors, including PCI Express, PCI, PMC, Compact PCI, and legacy SBus.
PCI Bus is the most widely used bus specification in use today. PCI slots are present in most Intel based computers, as well as Sun, HP, Silicon Graphics, IBM, and other workstations. PCI-X is a "superspec" of PCI and supports bus clock speeds of 66, 100, 133 and even potentially 512 MHz. EDT's older PCI boards are 33Mhz boards and will run at their rated speed in any PCI or PCI-X bus. Newer boards are 66Mhz and will run at their rated speed in any 66Mhz or faster PCI or PCI-X slot. They will also run in standard 33Mhz slots but with reduced maximum throughput.EDT PCI boards conform to the PCI version 2.2 standard. For more information and specifications, go to www.pcisig.com.
PMC and Compact PCI are essentially the same as PCI but in different form factors They are electrically the same as the PCI Bus, but the shape of the boards and the bus connectors are different. Designed for ruggedized implemenations, the PMC and Compact PCI form factors provide a secure mounting platform for PMC VME and Compact PCI mezzanine boards. PCMCIA to PMC bus extenders are also available.
EDT's PMC and Compact PCI products use the same software, firmware, and device drivers as their PCI Bus counterparts, and any applications written for EDT boards in one form-factor will work on equivalent products in other form-factors.
PCI Express is the latest high-speed bus specification. The mechanical specs are different than PCI or PCI-X so boards made for PCI or PCI-X won't work in a PCI Express slot, or vice-versa. EDT's PCI Express products use the same software, firmware, and device drivers as their PCI counterparts, and applications written for EDT boards of one type will work for the others.
Designed by Sun in 1989, the SBus board was for many years standard I/O interconnect for Sun computers, which typically run under the Solaris or SunOS flavor of the UNIX operating system. EDT continues to manufacture and support a number of SBus products, for use in legacy systems.
We have expanded our device driver support to include Windows NT/2000/XP™ (PCI and PMC products only) along with Solaris™ 2.x (SBus and PCI/PMC products) and Linux ™.
