6U VME VME64x Conduction- or Air-Cooled Dual PMC Carrier Card

The XChange4002 from Extreme Engineering Solutions (X-ES) is a versatile conduction- or air-cooled 6U VME64x dual-PMC carrier card. With PCI support between the two PMC slots and the VME64x 2eSST bridge, the XChange4002 is ideal for applications requiring the flexibility that PMC modules offer.

The XChange4002 implements its VME64x interface using an FPGA device for maximum product longevity and field upgradeability. The XChange4002 includes a local +3.3 V power supply, so backplane +3.3 V is not required. 32 pins of P14 I/O from each PMC site are routed to the P2 connector per VME-P2-a,c (ANSI/VITA 35-2000).
