3.3 V, Crystal to 100 MHz
Quad HCSL/LVDS PCIe
Clock Generator
The NB3N51054 is a precision, low phase noise clock generator that
supports PCI Express requirements. The device accepts a 25 MHz
fundamental mode parallel resonant crystal or a 25 MHz reference
clock signal and generates four differential HCSL/LVDS outputs (See
Figure 7 for LVDS interface) at 100 MHz clock frequency with
maximum skew of 40 ps. Through I2C interface, NB3N51054
provides selectable spread spectrum options of −0.35% and −0.5% for
applications demanding low Electromagnetic Interface (EMI) as well
as optimum performance with no spread option. The I2C interface
further enables control of each output and they can be enabled/
disabled individually.
