The PXH822 XMC 1.0 x16 Gen3 PCI Express XMC adapter expand the capabilities of embedded systems by enabling very low overhead, high throughput cabled PCIe expansion.

The adapters quad SFF-8644 cable connector supports the new PCI SIG External Cabling Specification 3.0. enabling connections to compliant Dolphin products and third party PCI Express cabled systems. The adapters can act as either hosts or targets when connecting to expansion chassis. They work in conjunction with other Dolphin products such as the PXH832 or MXH832/MXH833 PCI Express host adapter with standard cables. Additional scalability to large expansion systems can be created using the MXS824 switch. More information on cables for the PXH822.

A DIP switch on the card determines if the card operates as a upstream or downstream cable adapter and some other operational options. The PXH822 runs without the need for special device drivers, while supporting standard PCI Express devices and drivers. The PXH822 is bundled with The Dolphin Transparent Board Management tools. for monitoring and firmware upgrades.

The PXH822 and PXH826 also supports system clock isolation, by isolating the system clock. Users benefit from improved signal quality, reliability, and cable distances.

The PXH822 comes with Vita 42 XMC 1.0 connectors suitable for PCI Express Gen1 and 2. This will also work well in some PCIe Gen3 environments. The XMC connector provides 12 mm stacking height when assembled on a carrier/CPU board configured for 10 mm stacking heights. A proprietary bezel design allows this configuration to work without modifications to the front panel.

If you would like to utilize the Dolphin eXpressWare stack for PCIe NTB based communication, you need to purchase the PXH820 adapter card.

The XMC card is also prepared for READ-IO. Please contact Dolphin for specifications, variants and ordering information.
