Outputs and Internal
Termination
Description
The NB7L14M is a differential 1
to
4 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
LVPECL, CML, LVCMOS, LVTTL, or LVDS (See Table 6).
Differential 16 mA CML outputs provide matching internal 50
terminations, and 400 mV output swings when externally terminated
with 50 to V
CC
(See Figure 14).
The device is offered in a low profile 3x3 mm 16
pin QFN package.
Application notes, models, and support documentation are available at
www.onsemi.com.
