PEX430 PCI Express Switch and PMC/XMC Carrier Card
PEX430 allows designers to build complex VPX systems with multiple single board computers and multiple I/O modules.
It provides both a PCI Express switch and a mezzanine carrier.
The PCI Express capability of PEX430 allows up to four ports of 4-lane PCI Express to be connected to a non-blocking line-speed switch. The PEX430 switch supports non- transparent bridging mode to allow multiple hosts to be connected together.
The PCI Express switch also has an 8-lane PCIe port to the XMC site, or alternatively a 4-lane PCIe port to an PCI-X bridge for the PMC site.
