3.3 V, 156.25 MHz /
312.5 MHz LVPECL Clock
Oscillator
The single and 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 156.25 MHz or
312.5 MHz, ultra low jitter and phase noise LVPECL 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 1,000. Frequency stability options available as
either 50 PPM NBXDBA017, NBXSBA017, NBXHBA017
(Industrial Temperature Range) or 20 PPM NBXDBB017
(Commercial Temperature Range).

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 Ifpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
