NB4L6254
2.5V / 3.3V Differential
LVPECL 2x2 Clock Switch
and Low Skew Fanout
Buffer
Description
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 3.0 GHz.
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 highperformance computer, networking and
telecommunication systems, as well as onboard clocking of OC3,
OC12 and OC48 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 3.3 V or 2.5 V power
supply.
