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 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.
