NBXDBA014
3.3 V, 62.5 MHz / 125 MHz
LVPECL Clock Oscillator
The NBXDBA014 dual frequency crystal oscillator (XO) is
designed to meet today’s requirements for 3.3 V LVPECL clock
generation applications. The device uses a high Q fundamental crystal
and Phase Lock Loop (PLL) multiplier to provide selectable
62.5 MHz or 125 MHz, ultra low jitter and phase noise LVPECL
differential output. This device is a member of ON Semiconductor’s
PureEdget clock family that provides accurate and precision clock
solutions.
Available in 5 mm x 7 mm SMD (CLCC) package on 16 mm tape
and reel in quantities of 1,000.
Features
• LVPECL Differential Output
• Uses High Q Fundamental Mode Crystal and PLL Multiplier
• Ultra Low Jitter and Phase Noise − 0.4 ps (12 kHz − 20 MHz)
• Selectable Output Frequency − 62.5 MHz (default) / 125 MHz
• Total Frequency Stability − ±50 PPM
• Hermetically Sealed Ceramic SMD Package
• RoHS Compliant
• Operating Range 3.3 V ±10%
• This is a Pb−Free Device
Applications
• Fiber Distributed Data Interface
• Ethernet, Gigabit Ethernet
• Infiniband
• PCIe
• Host Bus Adapter
• RAID Controller
