The XChange4003 is a versatile conduction- or air-cooled 6U VME64x dual-XMC/PMC carrier card. With PCI and PCIe support between the two XMC/PMC slots and the VME64x 2eSST bridge, the XChange4003 is ideal for applications requiring the flexibility that XMC/PMC modules offer. The XChange4003 supports XMCs operating in both endpoint and root complex modes.The XChange4003 implements its VME64x interface using an FPGA device for maximum product longevity and field upgradeability. The XChange4003 includes a local +3.3 V power supply, so backplane +3.3 V is not required. 64 pins of P14 I/O from each XMC/PMC site are routed to the P2 and P0 connectors per P4V0-64 and P4V2-64ac (ANSI/VITA 35-2000).
