MultiLevel 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 32pin QFN package.
Application notes, models, and support documentation are available
at www.onsemi.com.
The NB7L585R is a member of the GigaCommfamily of high
performance clock products.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
5. Input and output parameters vary 1:1 with VCC.
6. RSECL outputs (Qn/Qn) loaded with 50 W to VCC – 2 V for proper operation.
7. Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously.
8. Vth is applied to the complementary input when operating in singleended mode.
9. VIHD, VILD, VID and VCMR parameters must be complied with simultaneously.
10. VCMR min varies 1:1 with GND, VCMR max varies 1:1 with VCC. The VCMR range is referenced to the most positive side of the differential
input signal.
