• PCi Express Design

    PCI Express Design (PCIe)

    This project was a RoHS compliant design that fit within a four physical lane PCI Express (PCIe) form factor as defined in the PCIe 2.0 specification. The height of the card was allowed to extend past the specification limits to accommodate the placement and routing of the four DDR2 memory DIMM sockets. This design was […]

  • 72 Port Infiniband Switch

    72 Line Infiniband Switch

    The primary purpose of 72 Port Switch Card is to reduce cable count and complexity in highly integrated Infiniband switch systems. This approach was initially utilized to create a switching matrix as the heart of a supercomputer. The 72 Port Switch Card is a subset of the full design and was meant to support localized […]

  • Signal integrity Analysis

    Signal Integrity Analysis

    A Critical Component to High Speed Design As signal speeds increase, the quality and integrity of the PCB layout becomes increasingly critical for optimizing the performance of the system. Simulation and analysis can help to avoid the painful hours of debug in a lab to find the source of bit errors, when you determine you […]

  • Digital Driver Detector

    Digital Driver Detector

    Overview of a Complete Board Redesign The Digital Driver Detector (DDD) board was part of a low cost test platform for mixed signal, analog, linear and discrete devices. It was redesigned to eliminate component obsolescence, use all SMT devices for manufacturing ease and solve low frequency (< 1MHz) gaps or dead zones for driving and […]
