NB3N51034
3.3V, Crystal to 100MHz/
200MHz Quad HCSL/LVDS
Clock Generator
The NB3N51034 is a high precision, low phase noise clock generator
that supports spread spectrum designed for PCI Express applications.
This device takes a 25 MHz fundamental mode parallel resonant crystal
and generates 4 dif ferential HCSL/L VDS outputs at 100 MHz or
