Low Jitter

VB7-Series

LVPECL VCXO

Description

Features:

The Connor-Winfield VB7 Series models

are 3.3V SMT 5.0x7.0mm Voltage Con-

trolled Crystal Oscillators (VCXOs)with ultra

low jitter. With LVPECL differential outputs,

the VB7 Series is designed for applications such

as SONET, WiMax, Fiber Channel where high

performance and low noise are needed.
