Crystal oscillator clock modules offer dual voltage capabilities

ON Semiconductor has expanded its PureEdge portfolio of silicon based crystal oscillator clock modules with the addition of six new devices.

The NBX series is designed to provide a cost effective, high accuracy reference clock solution with dual voltage capabilities and leading total frequency stability as low as ±20ppm. The new devices meet clock generation requirements in the latest 2.5/3.3V low voltage positive emitter coupled logic (LVPECL) designs for applications in routers, switches, servers and basestations.

The devices support frequencies for applications such as SONET, Gigabit Ethernet and lan/wlan. ON claims the series offers equivalent or better performance compared to quartz based third overtone XOs or surface acoustic wave products. This is complimented by an ultra low phase noise of -160 decibels relative to the carrier per hertz (dBc/Hz), typical RMS phase jitter of 0.5ps 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 622.08MHz for the NBXMBB024 and NBXSBB024, 156.25MHz for the NBXHGA017, 125.00MHz for the NBXHGA019, 161.1328MHz for the NBXSGA008 and 50.00MHz for the NBXHGA053.
