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.
