The IXH620 XMC cable adapter enables high speed PCI Express inter-system connections to external systems including servers, single board computers, and I/O subsystems. The IXH620’s 40Gbit/s throughput and sub one microsecond latency deliver superior performance and low latency to systems supporting standard XMC slots or XMC VPX, VME or cPCI carrier boards. The IXH620’s x8 cable connection uses an iPass™connector as a standardized connection method. The XMC adapter supports either upstream or downstream target configurations. To connect remote I/O or processing, the IXH620 implemented IDT®’s transparent or non-transparent bridging (NTB) functions. Used in transparent mode, standard PCI Express devices and drivers require no modifications. In NTB mode, the adapter facilitates inter-processor communication through Programmed IO (PIO) or Remote Direct Memory Access (RDMA).
