NB3N51032: Clock Generator, 3.3 V, Crystal to 25 MHz, 100 MHz, 125 MHz and 200 MHz Dual HCSL/LVDS

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, 100MHz, 125 MHz or 200 MHz clock frequencies. Outputs can interface with LVDS with proper termination. The NB3N51032 provides selectable spread options of - 0.5% and - 0.75% for applications demanding low Electromagnetic Interference (EMI). No spread setting is also available.
