Description
The NB7L585 is a differential 1:6 LVPECL 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 NB7L585 produces six identical output copies of Clock or Data
operating up to 5 GHz or 8 Gb/s, respectively. As such, NB7L585 is
ideal for SONET, GigE, Fiber Channel, Backplane and other
Clock/Data distribution applications.
The NB7L585 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 NB7L585 is a member of the GigaComm⢠family of high
performance clock products.
