SK3-MEDLEY

CompactPCI® Serial • XMC Module Carrier
PCI Express® 1 to 8 Lane Support

 

The SK3-MEDLEY is a peripheral slot board for PICMG® CompactPCI® Serial systems and acts as carrier card for an XMC-style mezzanine module. XMC modules are specified by ANSI/VITA 42/61, as an advanced replacement for PMC modules. While using a similar form factor as PMC cards, XMC modules are provided with a PCI Express® interface.

The SK3-MEDLEY is equipped with a bidirectional 8-lane PCI Express® Gen3 redriver, for optimum 8GT/s high speed signal integrity, and should be installed into a fat pipe peripheral slot of a CompactPCI® Serial backplane. The SK3-MEDLEY can be used with 74x139mm2 shortened length XMC mezzanine cards only (for 149mm length consider the SK2-SESSION).

 

The SK3-MEDLEY requires at least a single PCI Express® lane from the backplane, passed over across the connector P1 to a PCIe redriver circuit. Up to eight PCI Express® lanes are supported, when the SK3-MEDLEY is installed into a CompactPCI® Serial fat pipe peripheral slot (P1/P2 backplane connectors in use). With a total link bandwidth of 64Gbps, even very demanding applications can be realized, such as a 10/40GBps Ethernet or USB 3.1 XMC mezzanine module e.g.

The on-board 8-lane bidirectional redriver is suitable up to 8.0Gbps (PCIe 3.0) data transfer rate per lane, and ensures optimum signal integrity (wider opening with respect to the eye diagrams). The XMC module connector J15 is directly tied to the redriver circuit. In addition, a zero delay PCIe Gen3 clock buffer is provided on-board. Due to space restrictions on the SK3-MEDLEY imposed by the backplane connector P2, only 139mm length XMC mezzanine modules can be populated.
