The Freescale MC100ES6254 is a bipolar monolithic differential 2x2 clock
switch and fanout buffer. Designed for most demanding clock distribution
systems, the MC100ES6254 supports various applications that require a large
number of outputs to drive precisely aligned clock signals. The device is capable
of driving and switching differential LVPECL signals. Using SiGe technology and
a fully differential architecture, the device offers superior digital signal
characteristics and very low clock skew error. Target applications for this clock
driver are high performance clock/data switching, clock distribution or data
loopback in computing, networking and telecommunication systems.

Functional Description
MC100ES6254 is designed for very skew critical differential clock distribution
systems and supports clock frequencies from DC up to 3.0GHz. Typical
applications for the MC100ES6254 are primary clock distribution, switching and
loopback systems of high-performance computer, networking and
telecommunication systems, as well as on-board clocking of OC-3, OC-12 and
OC-48 speed communication systems. Primary purpose of the MC100ES6254 is
high-speed clock switching applications. In addition, the MC100ES6254 can be
configured as single 1:6 or dual 1:3 LVPECL fanout buffer for clock signals, or as
loopback device in high-speed data applications.
The MC100ES6254 can be operated from a 3.3 V or 2.5 V positive supply
without the requirement of a negative supply line.
