The PureEdge family of silicon-based voltage-controlled crystal oscillators (VCXOs) from On Semiconductor reduces costs and provides ultra-low jitter and phase noise compared to alternative solutions, the company says. According to On Semi, the NBVSBAxx series is ideal for providing low-jitter, stable reference clock in networking, SONET, 10-Gbit Ethernet, basestations, and broadcasting equipment.

The NBVSBAxx devices are designed to meet the requirements of 2.5- and 3.3-V low-voltage positive emitter coupled logic (LVPECL) clock generation applications offering a low-jitter (0.5 ps) reference clock (see the figure). The ability to power these devices with a 2.5- or 3.3-V supply enables design flexibility and simplifies the product bill of materials, driving further system cost reduction, the company says.

A High Q fundamental mode pullable crystal and phase-locked loop (PLL) multiplier is used to provide industry-standard frequencies from 60 to 700 MHz with a guaranteed pullable range of ±100 ppm and frequency stability of ±50 ppm. Also, these oscillators offer a tri-state enable/disable feature, allowing the user to turn the output on and off across the entire industrial temperature range of –40°C to 85°C.

The PureEdge NBVSBAxx VCXOs from On Semiconductor meet the requirements of 2.5- and 3.3-V LVPECL clock generation applications offering a low-jitter (0.5 ps) reference clock.

The NBVSBAxx devices come in a hermetically sealed 5.0- by 7.0- by 1.9-mm ceramic CLCC-6 surface-mount device (SMD) package. They cost $6.50 each in lots of 1000 units.
