Clock Driver 2-IN LVPECL 32-Pin QFN EP Rail

The NB7L585 is a differential 1:6 LVPECL Clock/Data distribution chip featuring a 2:1 Clock/Data input multiplexer with an input select pin. The INx/INxb inputs incorporate internal 50-ohm termination resistors and will accept LVPECL, CML, or LVDS logic levels. The NB7L585 produces six identical output copies of Clock or Data operating up to 5 GHz or 8 Gbps, respectively. As such, NB7L585 is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The NB7L585 is powered with either 2.5 V or 3.3 V supply. The NB7L585 is a member of the GigaComm family of high performance clock products.
