ON Semiconductor is extending its silicon-based crystal
oscillator (XO) clock module range. The six new additions to the NBX
series provide a cost-effective, high accuracy reference clock solution
with dual voltage capabilities and class-leading total frequency
stability as low as ±20 parts per million (ppm).
The new devices meet clock generation requirements in the latest 2.5 V /
3.3 V low-voltage positive emitter coupled logic (LVPECL) designs for
applications in routers, switches, servers, and basestations.
The new devices support frequencies for applications such as SONET,
Gigabit Ethernet, and LAN/WLAN. The NBX series offers equivalent or
better performance compared to quartz-based third overtone XOs or
surface acoustic wave (SAW) products. This is underlined by ultra-low
phase noise of -160 decibels relative to the carrier per hertz (dBc/Hz),
typical RMS phase jitter of 0.5 ps, and a low bit error rate.
New frequencies supported are 622.08 MHz for the NBXMBB024 and
NBXSBB024; 156.25 MHz for the NBXHGA017; 125.00 MHz for the NBXHGA019;
161.1328 MHz for the NBXSGA008; and 50.00 MHz for the NBXHGA053.
Availability and Pricing
The NBX devices are packaged in Pb-free, RoHS compliant, hermetically
sealed 5.0 mm x 7.0 mm x 1.9 mm ceramic CLCC-6 SMD packages. Budgetary
pricing for these products is $3.00-$5.50 per unit for quantities of
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.
