NB3N5573
3.3V, Crystal - To- HCSL
Clock Generator
Description
The NB3N5573 is a high precision, low phase noise clock generator
that supports PCI Express and Ethernet requirements. The device
takes a 25 MHz fundamental mode parallel resonant crystal and
generates differential HCSL output at 25 MHz, 100 MHz, 125 MHz or
200 MHz clock frequencies.
This device is housed in 5.0 mm x 4.4 mm narrow body TSSOP 16
pin package.
