NB7L1008
2.5V / 3.3V 1:8 LVPECL
Fanout Buffer
Multi−Level Inputs w/ Internal
Termination
Description
The NB7L1008 is a high performance differential 1:8 Clock/Data
fanout buffer. The NB7L1008 produces eight identical output copies
of Clock or Data operating up to 7 GHz or 12 Gb/s, respectively. As
such, the NB7L1008 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 NB7L1008 to
accept various logic standards, such as LVPECL, CML, LVDS 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
NB7L1008 is a member of the GigaCommfamily of high
performance clock products.
