Introduction

Electrical Requirements

The voltage and current requirements for the PMCspan are as follows:

Product Reliability (MTBF)

The reliability for the PMCspan is 75,000 hours MTBF.

VME Processor/PMCspan System

Figure 1-4 shows a block diagram of a PMCspan system: a VME processor

module, a PMCspan-001/-002 primary PMC carrier module, and a

PMCspan-010 secondary PMC carrier module.

The primary PMCspan interfaces to the VME processor module via the

PCI expansion connector. The expansion connector on the secondary bus

supports the secondary PMCspan. The PCI-to-PCI Bridge chip on the

PMCspan provides the interface between the primary PCI bus and the

secondary PCI bus.
