The NB3N3002 and NB3N5573 3.3 v clock generators create selectable 25, 100, 125, and 200 MHz clocks with host clock signal levels (HCSL) and sub-ps jitter. They target PCI Express, GigaBit Ethernet, and FBDIMM applications.
The NB3N3002 generates one differential HCSL output clock, while the NB3N5573 delivers dual outputs and improved jitter performance. They use a low cost 25 MHz crystal and yield clocks with phase noise of -130 dBc/Hz, relative to the carrier, at a 100 KHz offset and come in a 5.0 x 4.4 mm TSSOP-16 package.
