CompactPCI® • XMC Module Carrier

The CK2-SESSION is a peripheral slot board for PICMG® CompactPCI® Classic systems and acts as carrier card for a XMC-style mezzanine module. XMC modules are specified by ANSI/VITA 42, and can be considered as an improved replacement for PMC modules. While using the same form factor as PMC cards, XMC modules are provided with a PCI Express® interface.

The CK2-SESSION is equipped with a PCI® to PCI Express® bridge, for conversion of data from the parallel CompactPCI® backplane, to the on-board PCIe serial link. Due to bandwith limitations on the classic cPCI backplane, a single PCI Express® lane is sufficient for data I/O. Hence, the CK2-SESSION is well suited as a carrier for low to medium performance XMC modules (UART, Ethernet and other I/O).



The CK2-SESSION is a CompactPCI® classic peripheral slot card for 32-bit backplane systems (J1 connector), either 33MHz or 66MHz operated. The cPCI backplane delivers a maximum throughput of ~1Gbps @ 33MHz clock, which would be sufficient for medium speed I/O such as analog frontend, parallel port, RS-485, RS-232, USB2 or Gigabit Ethernet.

The on-board PCI to PCI Express® bridge is wired to the XMC module connector J15. A single PCIe lane delivers up to 2.5Gbps data transfer rate according to PCIe 1.0, which is limited however by the backplane bottleneck. For applications with demand for higher throughput, consider the SK2-SESSION as an alternate XMC module carrier (4 x 5Gbps).
