NB3N51044 3.3 V, Crystal to 100 MHz / 125 MHz Quad HCSL / LVDS Clock Generator The NB3N51044 is a precision, low phase noise clock generator that supports PCI Express and sRIO clock requirements.

The device accepts a 25 MHz fundamental mode parallel resonant crystal or a 25 MHz single ended reference clock signal and generates four differential HCSL/LVDS outputs (See Figure 10 for LVDS interface) of 100 MHz or 125 MHz clock frequency based on frequency select input F_SEL.
