Samtec has released an interactive "High Speed Cable Assembly Builder" program at www.samtec.com that makes it as easy as a "click" to create valid Samtec High Data Rate Cable part numbers. The program currently allows specification of high speed Q Strip assemblies on 0.5mm and 0.8mm pitch (HQCD & EQCD Series) and JTAG interfaces (HHSC Series) on .100" (2,54mm) pitch. Standard options such as cable length, wiring configuration, and screw features for rugged applications are easily specified with the program. Assemblies are manufactured with 38 AWG low dielectric constant (dk=2.1) micro co-ax cable. They are ideal for longer lengths up to 18", high flexing applications up to 40,000 cycles, and small bend radii of 2.5mm of less. These assemblies also offer low skew and superior EMI performance. Solder joints are fully encapsulated for added reliability. EQSD systems perform up to 1.1GHz at 18" given a -3dB insertion loss. HQCD systems perform up to 737MHz at 18" given a -3dB insertion loss.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
