ON Semiconductor Announces Expansion of PureEdge™ Family of Single and Dual Frequency Crystal Oscillator Modules with LVDS InterfaceSingle- and dual-frequency oscillator modules deliver high precision performance for LVDS and LVPECL 2.5 V and 3.3 V clock generation applications
PHOENIX, Ariz. – Sept. 22, 2009 - ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high performance, energy efficient, silicon solutions, has expanded its PureEdge™ family of high accuracy crystal oscillator (XO) clock modules. The new high precision devices provide total frequency stability of ±50 parts per million (ppm) and will meet clock generation requirements in next generation low-voltage differential signaling (LVDS) and low-voltage positive emitter coupled logic (LVPECL) designs.
The NBXzzzzzz series of single- and dual-frequency modules provide ultra low jitter and ultra low phase noise LVDS and LVPECL differential outputs respectively. Applications include frequency control and high accuracy clock trees in high speed LAN and WAN networking equipment, telecom base stations, storage systems and high-end computing platforms.
All of the new modules use a low frequency, high Q fundamental mode crystal and analog Phase Lock Loop (PLL) multiplier to provide the high accuracy single- or dual-output frequency. Typical RMS phase jitter is rated at just 0.5 picoseconds (ps) when output Single Side Band (SSB) is integrated between 12 kilohertz (kHz) and 20 megahertz (MHz). Output frequency options for single frequency modules are 161.13 MHz; 175.00 MHz; 187.50 MHz; 340.00 MHz; 425.00 MHz; 622.08 MHz. Dual frequency modules offer user selectable output frequency of 106.25 MHz/212.50 MHz; 125 MHz/250 MHz; 155.52 MHz/311.04 MHz; 156.25 MHz/312.50 MHz; 200.00 MHz/400.00 MHz. As a result, designers can choose modules that are optimized for a variety of specific protocols including Ethernet, Gigabit Ethernet, 1x and 2x Fibre Channel, SATA, SONET/SDH and PCIe.
“Delivering high precision across a variety of operating conditions, ON Semiconductor’s latest PureEdge clock modules provide the accuracy and reliability demanded by new and emerging LVDS and LVPECL clock tree designs,” said Ryan Cameron, director, custom industrial and timing products business unit at ON Semiconductor. “What’s more, these silicon based devices are simpler to manufacture and offer more flexibility with better performance and lead time than conventional quartz-based alternatives, helping OEMs to reduce costs without sacrificing performance.”
All of the new modules operate from a 2.5 volts (V) and 3.3 V input voltage and are supplied in a hermetically sealed 5.0 mm x 7.0 mm x 1.90 mm ceramic CLCC-6 SMD package.
