Description
The NB7L14 is a differential 1:4 LVPECL fanout buffer. The
NB7L14 produces four identical LVPECL output copies of Clock or
Data operating up to 7 GHz or 10.7 Gb/s, respectively. As such, the
NB7L14 is ideal for SONET, GigE, Fiber Channel, Backplane and
other Clock or Data distribution applications.
The differential inputs incorporate internal 50 W 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 capacitor−coupled differential or
single−ended input signals. The 1:4 fanout design was optimized for
low output skew applications.
The NB7L14 is a member of the GigaComm™ family of high
performance clock products.
