11 Myths About Signal Integrity in OpenVPX Backplane Design
Common Misconceptions About Signal Integrity in High-Density Backplanes: the backplane manages much of the interconnect between various circuit boards or cards across a system. By cramming more electrical connections into the same footprint, high-density backplanes seem to invite signal integrity (SI) issues, making some embedded designers skeptical about how to best move this influx of data within their applications. Here, we explore what can be accomplished using a high-density backplane, while preserving signal integrity across the network.
Chassis Management for OpenVPX and SOSA Systems
White paper discusses chassis management and monitoring chassis health in embedded systems deployed in military applications, using boards or plug-in cards designed to the OpenVPX standard or aligned to the SOSA standard.
Every millimeter counts: right-sizing for instrument cases
Whether in a lab, an industrial setting, or a mobile vehicle, instruments need to be increasingly smaller. In designing instrument cases, exact measurements are critical to maximize size, weight and performance. So how can this be done without high costs tooling, and how can costs be kept low for prototypes or low volumes?
OpenVPX cooling solutions
As processors and FPGAs enable more capability, the 3U VPX form factor is being favored for its reduced size and weight. The increasingly denser performance however,brings cooling challenges to implementing systems using a 3U card. This paper examines what types of cooling options are available and how they can be implemented.
Optimizing Power Conversion in High-Reliability Rugged Embedded Systems
This white paper discusses supplying power for today’s highly mobile, highly rugged embedded computing environments, going well beyond just a simple power supply unit (PSU). While an integrated PSU is key to system operation, dense electronics are demanding more power than can reasonably be supplied from just one power source.
Packaging and functional considerations for mobile communication equipment
Mobile networking systems require solutions tailored to a range of challenging operating environments, and often with severe space limitations. These parameters can pose challenges in the design of the enclosure. This paper presents ways to address these challenges and discusses the mobile networking protocols required for seamless secure connectivity.
