PXH822 High Level Specification
The PXH822 is a PCI Express Gen3 x8 Transparent XMC adapter card that can be configured as a Transparent Host Adapter card or a
Target Target adapter card. Once installed in any compliant XMC slot, the PXH822 can connect to another PXH822, MXH832,
MXH833 or PXH832 configured for Transparent Target operation or any target device compliant to the PCI Express External Cabling
Specification 3.0.
The PXH822 supports PCIe Gen1, Gen2 and Gen3 speeds and x1, x2, x4, x8 and x16 link-widths both at the XMC connector side and
cable link side. The card will operate at the highest common speed shared between the XMC Carrier card and the PXH822 (up to
Gen3) and the widest common link-width (up to x16 using both P15 and P16 XMC connectors).
