ON Semiconductor Expands PureEdge Single and Dual Frequency Crystal Oscillator Modules with LVDS Interface

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 FibreChannel, SATA, SONET/SDH and PCIe.
