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 50W 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 V REFAC
reference output can be used to rebias capacitor−coupled
differential or single−ended inputsignals. 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.
