NBXSBA021 Datasheet, PDF (1/6 Pages) ON Semiconductor – 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 3.3ĂV 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.
