NB6L14
2.5 V/3.3 V 3.0 GHz
Differential 1:4 LVPECL
Fanout Buffer
Multi- Level Inputs with Internal Termination
Description
The NB6L14 is a 3.0 GHz differential 1:4 LVPECL clock or data
fanout buffer. The differential inputs incorporate internal 50 W
termination resistors that are accessed through the VT pin. This feature
allows the NB6L14 to accept various logic standards, such as
LVPECL, LVCMOS, LVTTL, CML, or LVDS logic levels. The
VREF_AC 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 NB6L14 is a member of the ECLinPS MAX™ family of high
performance clock and data management products.
