Mux Input to 1:6 CML
Clock/Data Fanout

MultiLevel Inputs w/ Internal Termination
Description
The NB7V585M is a differential 1to6 CML 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 (see Figure 9). The NB7V585M produces six identical output
copies of clock or data operating up to 6 GHz or 10 Gb/s, respectively.
As such, NB7V585M is ideal for SONET, GigE, Fiber Channel,
Backplane and other clock/data distribution applications. The 16 mA
differential CML output structure provides matching internal 50 W
source terminations, 400 mV output swings when externally
terminated with a 50 W resistor to VCC (see Figure 14) and is
optimized for low skew and minimal jitter. The NB7V585M is
powered with either 1.8 V or 2.5 V supply and is offered in a low
profile 5x5 mm 32pin QFN package.
Application notes, models, and support documentation are available
at www.onsemi.com.
The NB7V585M is a member of the GigaCommfamily of high
performance clock products.

EP
The Exposed Pad (EP) on the QFN32 package bottom is thermally connected to the
die for improved heat transfer out of package. The exposed pad must be attached to a
heatsinking conduit. The pad is electrically connected to the die, and must be electric-
ally and thermally connected to GND on the PC board.
1. In the differential configuration when the input termination pins (VT0, VT1) are connected to a common termination voltage or left open, and
if no signal is applied on INn/INn input, then, the device will be susceptible to selfoscillation. Qn/Qn outputs have internal 50 W source
termination resistors.
2. All VCC and GND pins must be externally connected to a power supply for proper operation.
