NBXDBB018/D

NBXDBB018, NBXDBA018

3.3 V, 155.52 MHz /

311.04MHz 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 PureEdge

t 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).
