Wayne, N.J. Cardinal Components Inc. now has surface-mount TCXOs and VC-TCXOs in 2.5-mm high, leadless packages. They can be specified with sine-wave or square-wave output, with or without a voltage-control option. The CT4 and CT6 series have a standard stability vs. temperature specification of plus/minus2.5 ppm over a range of -30degrees to 75degreesC. The oscillators can also be supplied with even tighter stability of plus/minus1.5 ppm over -20degrees to 70degreesC. Different supply-voltage levels are also available, with 3 V or 5 V standard.
Pricing per 1,000 is approximately $6.50 each. Delivery lead times are running eight to nine weeks.
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.
