Product Information

The Technobox, Inc. P/N 3390 PMC-to-PCI Adapter for Test is an active extender that accommodates live insertion of one PCI Mezzanine Card (PMC) in a PCI slot for performance analysis and testing. Both sides of the PMC under test are readily accessible. The adapter may be used for both development and production testing. In production applications, use of a Technobox, Inc. PMC Socket Saver (P/N 4690) is recommended to preserve the adapter’s PMC connectors. Both 32- and 64-bit PCI bus systems are supported. The adapter’s edge-finger connector is universally keyed for 3.3- and 5-volt signaling. Furthermore, the keying pegs have been removed so that PMCs with either 3.3- or 5-volt signaling can be mounted.

Power to the PMC under test can be toggled using an ON/OFF switch that is mounted on the top edge of the adapter. This eliminates powering the platform system on and off whenever a PMC is installed or removed. Soft-start sequencing and special circuits, including CMOS-based, zero propagation Quick Switches, protect against voltage and current transients and assure that the PMC is effectively isolated from the PCI bus during power on/off sequencing. These circuits prevent system crashes or hanging up the PCI bus when applying power.
