NB3Nxxxxx - VCXO Series

3.3V PureEdge

] VCXO

Clock Generator with

Differential LVPECL Outputs

Description

The NB3NXXXXX − series voltage−controlled crystal oscillator

(VCXO) devices are designed to meet today’s requirements for 3.3 V

LVPECL clock generation applications. These devices use an external

high Q fundamental mode pullable crystal and Phase Locked Loop

(PLL) multiplier to provide a wide range of frequencies from 60 MHz

to 700 MHz (factory configurable per user specifications) with a

pullable range of

±100 ppm. The silicon−based PureEdge products

provides users with exceptional frequency stability and reliability.

They produce an ultra low jitter and phase noise LVPECL differential

out put . The NB3NXXXXX − series are members of

ON Semiconductor’s PureEdge clock family that provides accurate

and precision clock generation solutions.

Available in the industry standard 4 mm x 4 mm QFN−20 package.
