Description
www.onsemi.com
The NB4N11M is a differential 1−to−2 clock/data
distribution/translation chip with CML output structure, targeted for
high−speed clock/data applications. The device is functionally
equivalent to the EP11, LVEP11, SG11 or 7L11M devices. Device
produces two identical differential output copies of clock or
data signal operating up to 2.5 GHz or 2.5 Gb/s, respectively. As such,
NB4N11M is ideal for SONET, GigE, Fiber Channel, Backplane and
other clock/data distribution applications.

current–mode logic (CML) compatible levels when receiver loaded
with 50 W or 25 W loads connected to 1.8 V, 2.5 V or 3.3 V supplies
(see Figure 19). This simplifies device interface by eliminating a need
for coupling capacitors.
The device is offered in a small 8−pin TSSOP package.
