As spatial requirements become more critical in telecommunications, computer, military and rail systems, Tyco Electronics developed the STRADA Mesa mezzanine connector to offer a stacking, board-to-board connection solution for efficient PCB space utilization. The STRADA Mesa product design offers the market a stacking connector that delivers a high-speed performance of +15 Gbps.
In addition, the design provides three pin and socket signal contact arrangement options, high-speed differential, high-density single-ended and RF/ Coaxial, to suit various application requirements.
Stack height options start at 8mm and grow to 42mm in 1mm increments, making the connector ideal for high-speed differential architectures utilizing PCBs arranged in a mezzanine application. The product solves power issues associated with board-to-board stacking through integrated power contacts that are each capable of carrying 14A of current.
The STRADA Mesa connector is available in eight pairs per column and in sizes one, two and three, which when fully loaded with differential pairs, will yield 40, 80 and 120 pairs, respectively. The product design incorporates a pin and socket separable interface and a press-fit PCB attachment, creating an ideal condition for mating multiple connectors simultaneously. Additional features include optional open space for airflow and optional guide systems to accommodate blind mating.
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.
