Sunnyvale, Calif. The latest members of the high-speed LVDS SerDes family, the MAX9234, MAX9236, and MAX9238, are hot-swappable, 21-bit, dc-balanced LVDS deserializers. The devices deserialize three LVDS serial inputs into 21 single-ended LVTTL/LVCMOS outputs, and communicate over a three-wire twisted pair or differential line. Each part reduces the number of wires from 22 to 8, which simplifies the design and saves space and cost in system interconnects such as cables and backplanes. The hot-swappable capability increases fault tolerance and permits "on-the-fly" frequency programming. Advanced proprietary and integrated data coding reduce EMI. The LVDS outputs meet the requirements of the ANSI TIA/EIA 644 LVDS standard. The 9234 and 9236 are suited for driving 480- by 800-pixel resolutions displays, while the 9238's higher clock rate allows driving LCDs up to 768 by 1024 pixels. Prices start at $3.90.

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.
