2.5V/3.3V Differential LVPECL 2x2 Clock Switch And Fanout Buffer

MC100ES6254 is designed for very skew critical differential clock distribution systems and supports clock frequencies from DC up to 3.0 GHz. 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.
