NB4N11S
3.3 V 1:2 AnyLevel™ Input
to LVDS Fanout Buffer /
Translator
The NB4N11S is a differential 1:2 Clock or Data Receiver and will
accept AnyLevel
TM
input signals: LVPECL, CML, LVCMOS,
LVTTL, or LVDS. These signals will be translated to LVDS and two
identical copies of Clock or Data will be distributed, operating up to
2.0 GHz or 2.5 Gb/s, respectively. As such, the NB4N11S is ideal for
SONET, GigE, Fiber Channel, Backplane and other Clock or Data
distribution applications.
The NB4N11S has a wide input common mode range from
GND + 50 mV to V
CC
− 50 mV. Combined with the 50 W internal
termination resistors at the inputs, the NB4N11S is ideal for
translating a variety of differential or single−ended Clock or Data
signals to 350 mV typical LVDS output levels.
The NB4N11S is functionally equivalent to the EP11, LVEP11,
SG11 or 7L11M devices and is offered in a small 3 mm X 3 mm
16−QFN package. Application notes, models, and support
documentation are available at www.onsemi.com.
