NBXDBB018, NBXDBA018
3.3 V, 155.52 MHz /
311.04ꢀMHz LVPECL Clock
Oscillator
The NBXDBB018 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 155.52
MHz or 311.04 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 1000. Frequency stability options available as
either 50 PPM NBXDBA018 (Industrial Temperature Range) or
20 PPM NBXDBB018 (Commercial Temperature Range).
