ON Semiconductor today further expanded its PureEdge family of silicon-based voltage controlled crystal oscillators (VCXO) with six new devices. The NBVSPAXXX range of VCXO clock modules are designed to satisfy the exacting requirements set by modern 3.3 volt (V) low-voltage differential signalling (LVDS) clock generation applications. Targeted for use in communications infrastructure such as network routers, switches, servers, and base stations, these high performance devices utilize a high Q fundamental mode pull-able crystal and phase locked loop (PLL) multiplier to provide all industry standard output clock frequencies.

Frequencies supported are 156.25 megahertz (MHz) for the NBVSPA017 device, 155.52 MHz for the NBVSPA018, 125.00 MHz for the NBVSPA019, 160.00 MHz for the NBVSPA024, 148.50 MHz for the NBVSPA027, and 74.25 MHz for the NBVSPA042. Custom frequency versions are also available on request, covering frequencies from 60 MHz to 700 MHz.

The new devices have a pull-able range of ±100 parts per million (ppm), an orderable frequency stability of ±50 ppm and a typical jitter of just 0.5 picoseconds (ps) across the 12 kilohertz (kHz) to 20 MHz frequency range. They have a typical output rise time (20% to 80%) of 245 ps.

The VCXOs in NBVSXXXXX range are fully compliant with the MIL-STD-833 standard in terms of shock, vibration and thermal ruggedness. Each device has an industrial operating temperature range of −40 ⁰C to +85 ⁰C.

This announcement follows on from the company’s introduction of the NBVSBAxxx series of LVPECL VXCOs in the summer.

“Communication system designs are continuing to demand more highly advanced timing solutions,” stated Prescott Sakai, director of ON Semiconductor’s Clock & Data Products Group. “Traditional quartz-based products have now reached a point where their performance and cost are causing serious restrictions. ON Semiconductor’s full range of NBVSXXXXX silicon-based VCXO devices deliver equivalent performance to commonly used quartz-based products, but with considerably shorter lead times and lower unit costs, allowing customers to get their solutions to market quickly and with a reduced overall bill-of-materials.”

The NBVSPA017, NBVSPA018, NBVSPA019, NBVSPA027 and NBVSPA042 are offered in a Pb-free, hermetically sealed, 5.0 mm x 7.0 mm x 1.8 mm CLCC-6 package. They are priced at $5.70 per unit in 10,000 unit quantities.
