ON Semiconductor Releases High Performance Single And Dual Frequency Crystal Oscillator Modules

Phoenix, AZ - ON Semiconductor announced the expansion of its high performance clock and data management portfolio with the introduction of nine new PureEdge PLL based clock modules for crystal oscillator (XO) replacement. The NBXxxxx series of devices are ideal for high-speed networking, telecom, and high end computing applications.

"The new clock modules from ON Semiconductor represent the company's entry into the frequency control market, leveraging its long leadership position in high performance, ultra low jitter clock distribution," said Dan Huettl, ON Semiconductor general manager and director of the Advanced Logic Division. "These new silicon-based crystal oscillators are simpler to manufacture and provide superior jitter performance compared to expensive crystal oscillators. This supports lower overall system costs and shortened lead times."

The Devices
The new NBXSBA010, NBXDBA012, NBXDBA014, NBXDBA015, NBXDDA016, NBXDBA017, NBXDBA018, NBXSBA020 and NBXSBA021 crystal oscillator modules use a high Q fundamental mode crystal and analog Phase Lock Loop (PLL) multiplier to provide single or dual frequency, ultra low jitter and phase noise LVPECL/CML differential output. The NBXSxxx (single frequency) / NBXDxxx (dual frequency) family of crystal oscillators include the industry's best long-term time domain jitter performance and exceptional device noise floor of -163 dBc / Hz at 10 megahertz (MHz) offset with Phase RMS jitter of 0.4 picoseconds (ps) when integrated 12 hertz (Hz) to 20 MHz allowing bigger clock timing margins for whole system clock tree.

They create sub picosecond (ps) jitter quality clocks delivering single and/or dual frequency of 100 MHz, 106.25 MHz, 125 MHz, 155.52 MHz, 156.25 MHz, 200.00 MHz, 212.5 MHz, 250 MHz, 311.04 MHz and 312.5 MHz that are ideal for 1x/2x FibreChannel, SATA, iSCSI, PCIe, SONET / SDH, Ethernet and clock margining applications.

Key Features:

  • Power Supply – 3.3 V 10 percent
  • Low Phase RMS Jitter – 0.4 ps (12 kHz - 20 MHz)
  • Industry Best Period Jitter – RMS = 0.6 ps; Pk-Pk = 5 ps (JEDEC Standard – 10000 Cycles)
  • Industry Best Cycle to Cycle Jitter – RMS = 1 ps; Pk-Pk = 7 ps (JEDEC Standard – 1000 Cycles)
  • Output Clock Duty Cycle – 48 percent to 52 percent (Max)
