2.5V / 3.3V Differential 4:1 Mux Input To 1:2 LVPECL Clock/Data Fanout / Translator

The NB7L572 is a high performance differential 4:1 Clock Data input multiplexer and a 1:2 LVPECL Clock Data fanout Buffer The INx/INx inputs includes internal 50  termination resistors and will accept differential LVPECL, CML, or LVDs Logic levels. The NB7L572 incorporates a pair of Select pins that will choose one of four differential inputs and will produce two identical LVPECL output copies of Clock or Data operating up to 7 GHz or 10 Gb/s, respectively. As such, NB7L572 is ideal for SONET GigE, Fiber Channel, Backplane and other Clock Data distribution applications. The NB7L572 INx/INx inputs, outputs and core Logic are powered by a 2.5 V 5% V or 3.3 V 10% power supply. The two differential LVPECL outputs will swing 750 mV when externally terminated with a 50  resistor to VCC 2 V, and are optimized for low skew and minimal jitter. By ON Semiconductor
