Description
The NB7L14M is a differential 1to4 clock/data distribution chip
with internal source terminated CML output structures, optimized for
minimal skew and jitter. Device produces four identical output copies
of clock or data operating up to 8 GHz or 12 Gb/s, respectively. As
such, NB7L14M is ideal for SONET, GigE, Fiber Channel, Backplane
and other clock/data distribution applications.
Inputs incorporate internal 50
W termination resistors and accept
LVPECL, CML, LVCMOS, LVTTL, or LVDS (See Table 6).
Differential 16 mA CML outputs provide matching internal 50
W
terminations, and 400 mV output swings when externally terminated
with 50
The device is offered in a low profile 3x3 mm 16pin QFN package.
Application notes, models, and support documentation are available at
