NBXSBA021_09 Datasheet, PDF (1/6 Pages) ON Semiconductor – 3.3 V, 266.667 MHz LVPECL Clock Oscillator
NBXSBA021, NBXSBB021
3.3 V, 266.667 MHz LVPECL
Clock Oscillator
The NBXSBB021/NBXSBA021 single 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
266.667 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. Frequency stability options available as
either 50 PPM NBXSBA021 or 20 PPM NBXSBB021.
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)
• Output Frequency − 266.667 MHz
• Hermetically Sealed Ceramic SMD Package
• RoHS Compliant
• Operating Range 3.3 V ±10%
• Total Frequency Stability − ±20 PPM or ±50 PPM
Applications
• Servers
• Fully Buffered DIMM
