The NB3N51032 is a precision, low phase noise clock generator that supports PCI Express and Ethernet requirements. The device accepts a 25 MHz fundamental mode parallel resonant crystal and generates a differential HCSL output at 25 MHz, 100 MHz, 125 MHz or 200 MHz clock frequencies. Outputs can interface with LVDS with proper termination (See Figure 10). The NB3N51032 provides selectable spread options of -0.5% and -0.75% for applications demanding low Electromagnetic Interference (EMI) as well as optimum performance with no spread option. Features:
