Miami - Raltron Electronics Corp.'s 5 x 7-mm low-voltage differential-signaling clock oscillator, the CLD, boasts high-frequency specifications. LVDS is said to offer a cost-effective, multigigabit data transfer on copper cables or printed-circuit board traces. Coming in a surface-mount package, the clock oscillators provide jitter of 1 picosecond rms in a frequency range of 60 to 200 MHz, with frequency stabilities of plus/minus 20 ppm to plus/minus 100 ppm. The devices are available in a supply voltage of 3.3 volts at 40 milliamps maximum current consumption. An enable/ disable function is available.The CLD series of crystal oscillators is priced at $6 each in quantities of 1,000. Delivery is in six 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.
