The Technobox 5012 adapts a single PMC to a standard PCI or PCI-X environment. Featuring an Intel 31154 bridge chip, the 5012 accommodates both PMC (IEEE 1386.1) and PMC-X boards (VITA 39) of any signaling level, clock frequency, and bus width. The bridge assures PCI bus signal integrity even with multiple adapters plugged into a single PCI bus segment. Both the primary and secondary PCI busses support speeds of 33 and 66 MHZ as well as PCI-X speeds of 66/100/133 MHz. Furthermore, the bridge will translate transfer width, clock frequency, and protocol differences between the PCI busses. The user may select either 3.3V or 5V secondary PCI bus signaling levels using a jumper on the PMC-X to PCI-X adapter board. The 3.3V / 5V signaling level for the primary PCI bus is established by the VIO power rail on the PCI bus edge finger. Several LEDs visible from the back of the adapter indicate status of power (PVIO, SVIO, +12V, -12V, 5V, 3.3V) and key PCI bus signals. Form, fit, fucntion compatible with original Technobox P/N 4352.
