Multi−Level Inputs w/ Internal Termination
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.

LVPECL outputs will swing 750 mV when externally terminated with
a 50 W resistor to V
