NB6N14S
3.3 V 1:4 AnyLevelt
Differential Input to LVDS
Fanout Buffer/Translator
The NB6N14S is a differential 1:4 Clock or Data Receiver and will
accept AnyLevelt differential input signals: LVPECL, CML or
LVDS. These signals will be translated to LVDS and four identical
copies of Clock or Data will be distributed, operating up to 2.0 GHz or
2.5 Gb/s, respectively. As such, the NB6N14S is ideal for SONET,
GigE, Fiber Channel, Backplane and other Clock or Data distribution
applications.
The NB6N14S 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 NB6N14S is ideal for
translating a variety of differential or single−ended Clock or Data
signals to 350 mV typical LVDS output levels.
The NB6N14S 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.
The NB6N14S is a member of the ECLinPS MAXt family of high
performance products.
