ON Semiconductor expands PureEdge silicon-based crystal oscillator clock module portfolio

PHOENIX, USA: ON Semiconductor announced the further extension of 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 picoseconds (ps), and a low bit error rate.

“This frequency and voltage range expansion gives designers of LVPECL clock tree designs even greater choice,” said Ryan Cameron, director, custom industrial and timing products business unit at ON Semiconductor. “With improved performance, dual voltage flexibility and reduced lead times compared to quartz-based alternatives, the NBX series is keeping ahead of the increasing demands of applications in this sector.”

New frequencies supported are 622.08 megahertz (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.

The NBX devices are packaged in Pb-free, RoHS compliant, hermetically sealed 5x7x1.9mm ceramic CLCC-6 SMD packages. Budgetary pricing for these products is $3.00-$5.50 per unit for quantities of 1,000 units.
