CompactPCI® Express (PXI Express™) • PCI Express® Card Carrier

The EA4-COUNTRY is a peripheral slot board for PICMG® CompactPCI® Express systems and acts as carrier for a low profile PCI Express® Card. The EA4-COUNTRY is provided with a PCI Express® x8 connector (option x4, x1) and accommodates a PCIe® card with maximum dimensions of up to 176mm (length) x 68.9mm (height). Covered by a metallic hood, the PCI Express® Card protrudes with its bracket from the EA4-COUNTRY front panel, for optimum board space utilization.

The EA4-COUNTRY complies with the PICMG® EXP.0 specification and is also suitable for PXI Express™ systems. For best performance, the EA4-COUNTRY should be inserted into a CompactPCI® Express peripheral slot type 1 or 2, with a link width of PCIe® x8 on the backplane connector XP3. As power path for the PCI Express® card, the EA4-COUNTRY is equipped in addition with the backplane power connector XP1, as defined for CompactPCI® Express type 1 peripheral slots.
