NB7L1008M

2.5 V/3.3 V 1:8 CML Fanout Multi−Level Inputs w/ Internal Termination NB7L1008M Description The NB7L1008M is a high performance differential 1:8 Clock/Data fanout buffer. The NB7L1008M produces eight identical output copies of Clock or Data operating up to 6 GHz or 10.7 Gb/s, respectively. As such, the NB7L1008M is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The differential inputs incorporate internal 50 W termination resistors that are accessed through the VT pin. This feature allows the NB7L1008M to accept various logic standards, such as LVPECL, CML, LVDS, LVCMOS or LVTTL logic levels. The VREFAC reference output can be used to rebias capacitor−coupled differential or single−ended input signals. The 1:8 fanout design was optimized for low output skew applications. The NB7L1008M is a member of the GigaComm™ family of high performance clock products.
