Multi−Level Inputs w/ Internal Termination
Description
The NB7L72M is a high bandwidth, low voltage, fully differential
2 x 2 crosspoint switch with CML outputs. The NB7L72M design is
optimized for low skew and minimal jitter as it produces two identical
copies of Clock or Data operating up to 7 GHz or 10 Gb/s,
respectively. As such, the NB7L72M is ideal for SONET, GigE, Fiber
Channel, Backplane and other clock/data distribution applications.
The differential IN/IN inputs incorporate internal 50 W termination
resistors and will accept LVPECL, CML, or LVDS logic levels (see
Figure 11). The 16 mA differential CML outputs provide matching
internal 50 W terminations and produce 400 mV output swings when
externally terminated with a 50 W resistor to V_CC (see Figure 9).
The NB7L72M is the 2.5 V/3.3 V version of the and NB7V72M and
is offered in a low profile 3x3 mm 16−pin QFN package. Application
notes, models, and support documentation are available at
www.onsemi.com.
The NB7L72M is a member of the GigaComm™ family of high
performance clock products.
