PMC Voltage Adapter Now Available

Beyond Electronics, a technology leader providing rugged, real-time computing solutions to OEMs and system integrators, has introduced a PMC voltage adapter board. This board enables the use of legacy PMC boards on newer hosts as well as newer PMC boards on legacy host systems. Because many of the older PMC board designs connected their VCCio to 5 Volts, they cannot be plugged into a board with 3.3 Volt I/O or even in some hosts with universal I/O without damaging the host power supplies or causing serious damage. The PMC-VA has on-board level translators that adapt the voltage levels of all PCI signal lines to the appropriate levels. The board will also adapt 3.3 Volt PMC boards to 5 Volt host systems. A jumper on the front of the board allows selection of the required PMC VCCio Voltage.
In the event that the VCCio is incorrectly set, an on-board fuse will help protect the system power supplies.

The board comes standard with all four PMC connectors installed, but because some legacy PMCs had either two or four connectors and had components where the other connectors would reside, the board can be ordered with any preferred connector population option.

The board has been tested extensively across a temperature range of -40 to +85C. It is available for 32 or 64 bit PCI systems and is ready for immediate shipment.
