Silicon-based VCXOs

15 September 2010 Electronics Technology

New from ON Semiconductor is a PureEdge family of silicon-based voltage controlled crystal oscillators (VCXOs). The new NBVSBAxxx series is designed to provide a low-jitter, stable reference clock in designs such as networking, SONET, 10 Gigabit Ethernet, base stations and broadcasting equipment.

The devices are designed to meet the requirements of 2,5 V and 3,3 V low voltage positive emitter coupled logic (LVPECL) clock generation applications offering a low-jitter (0,5 ps) reference clock. A high-Q fundamental mode pullable crystal and phase locked loop (PLL) multiplier is used to provide industry standard frequencies across a wide range of 60 MHz to 700 MHz with a guaranteed pullable range of ±100 ppm and frequency stability of ±50 ppm. The 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.
