NB7L572

NB7L572 2.5V / 3.3V Differential 4:1 Mux Input to 1:2 LVPECL Clock/Data Fanout / Translator Multi−Level Inputs w/ Internal Termination 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 W 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 W resistor to VCC – 2 V, and are optimized for low skew and minimal jitter. The NB...
