PXH820 High Level Specification
The PXH820 is a PCI Express Gen3 x8 NTB XMC adapter card available from Dolphin providing an easy-to-use, multi-functional PCI
Express networking solution.
The PXH820 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 PXH820 (up to
Gen3) and the widest common link-width (up to x16 using both P15 and P16 XMC connectors). The PXH820 is link compliant to the
PXH830 card. These two products can be mixed in any supported combination to create a PCIe fabric consisting of standard servers
with a standard PCIe slot and embedded systems supporting the XMC form factor. Scale out solutions can be implemented using
the 24 port MXS824 PCIe switch.
