NB4L6254: 2x2 Clock/Data Switch and Fanout Buffer
The NB4L6254 is a differential 2x2 clock switch and drives precisely aligned clock signals through its LVPECL fanout buffers. It employs a fully differential architecture with bipolar technology, offers superior digital signal characteristics, has very low clock output skew and supports clock frequencies from DC up to 3.0GHz. The NB4L6254 is designed for the most demanding, skew critical differential clock distribution systems. Typical applications for the NB4L6254 are clock distribution, switching and data loopback systems of high-performance computer, networking and telecommunication systems, as well as on-board clocking of OC-3, OC-12 and OC-48 communication systems. In addition, the NB4L6254 can be configured as a single 1:6 or dual 1:3 LVPECL fanout buffer. The NB4L6254 can be operated from a single 3.3V or 2.5V power supply.
