NBVSBAXXX Series
2.5 V/3.3 V, LVPECL
Voltage-Controlled Crystal
Oscillator (VCXO)
PureEdget Product Series
The NBVSBAXXX series voltage−controlled crystal oscillator
(VCXO) devices are designed to meet today’s requirements for 2.5 V
and 3.3 V LVPECL clock generation applications. These devices use a
high Q fundamental mode 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 and a frequency stability of
±50
ppm. The
silicon−based PureEdget products design provides users with
exceptional frequency stability and reliability. They produce an ultra
low jitter and phase noise LVPECL differential output.
The NBVSBAXXX series are members of ON Semiconductor’s
PureEdget clock family that provides accurate and precision clock
generation solutions.
Available in the industry standard 5.0 x 7.0 x 1.8 mm and in a new
3.2 x 5.0 x 1.2 mm SMD (CLCC) package on 16 mm tape and reel in
quantities of 1,000.
