VPX represents the future of VME. Eschewing the still-relevant 25 year old parallel bus backplane in favor of serial switched fabrics, VPX supports literally hundreds of user-defined I/O lines at speeds approaching 5 GHz. Also known as VITA 46, VPX has a companion specification called REDI (Ruggedization Enhanced Design Implementation, aka VITA 48). REDI is all about the mechanicals - 2-level maintenance, shielded card LRUs, cooling, and REDI even offers provisions for liquid flow-through cooling. Digging much deeper than the more common electrical aspects of VPX, this E-cast explores the myriad mechanical aspects of the two specifications, including backplane design, transition modules, and chassis implementations. If you are considering or designing with VPX/REDI – you’ll want to tune in just to hear what our experts have to say.
