ON Semiconductor NB7L14MN1TXG

Description
The NB7L14 is a differential 1:4 LVPECL fanout buffer. It produces four identical LVPECL output copies of Clock or Data operating up to 7 GHz or 10.7 Gb/s, respectively. The NB7L14 is ideal for SONET, GigE, Fiber Channel, Backplane, and other Clock or Data distribution applications.
The differential inputs incorporate internal 50 Ω termination resistors that are accessed through the VT Pin. This feature allows the NB7L14 to accept various logic standards, such as LVPECL, CML, LVDS, LVCMOS, or LVTTL logic levels. The VREFAC reference output can be used to rebias capacitorcoupled differential or singleended input signals. The 1:4 fanout design was optimized for low output skew applications.
The NB7L14 is a member of the GigaComm™ family of highperformance clock products.
