NB7L585R
2.5V/3.3V, 7GHz/10Gbps
Differential 2:1 Mux Input to
1:6 RSECL Clock/Data
Fanout Buffer / Translator
MultiâLevel Inputs w/ Internal
Termination
Description
The NB7L585R is a differential 1:6 RSECL Clock/Data distribution
chip featuring a 2:1 Clock/Data input multiplexer with an input select
pin. The INx/INx inputs incorporate internal 50 W termination
resistors and will accept LVPECL, CML, or LVDS logic levels.
The NB7L585R produces six identical output copies of Clock or
Data operating up to 7 GHz or 10 Gb/s, respectively. As such,
NB7L585R is ideal for SONET, GigE, Fiber Channel, Backplane and
other Clock/Data distribution applications.
The NB7L585R is powered with either 2.5 V or 3.3 V supply and is
offered in a low profile 5mm x 5mm 32âpin QFN package.
Application notes, models, and support documentation are available
at www.onsemi.com.
The NB7L585R is a member of the GigaComm⢠family of high
performance clock products.
