NBXDPA017
2.5 V / 3.3 V, 156.25 MHz /
312.5 MHz LVDS Clock
Oscillator
The NBXDPA017 dual frequency crystal oscillator (XO) is
designed to meet today’s requirements for 2.5 V and 3.3 V LVDS
clock generation applications. The device uses a high Q fundamental
crystal and Phase Lock Loop (PLL) multiplier to provide selectable
156.25 MHz or 312.5 MHz, ultra low jitter and phase noise LVDS
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.
