NB7V72M
1.8V / 2.5V Differential 2 x 2
Crosspoint Switch with
CML Outputs Clock/Data
Buffer/Translator
MultiLevel Inputs w/ Internal Termination
Description
The NB7V72M is a high bandwidth, low voltage, fully differential
2 x 2 crosspoint switch with CML outputs. The NB7V72M design is
optimized for low skew and minimal jitter as it produces two identical
copies of Clock or Data operating up to 5 GHz or 6.5 Gb/s,
respectively. As such, the NB7V72M 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 10). 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 VCC (see Figure 11). The
NB7V72M is the 1.8 V/2.5 V CML version of the NB7L72M and is
offered in a low profile 3x3 mm 16pin QFN package. Application
notes, models, and support documentation are available at
www.onsemi.com.
The NB7V72M is a member of the GigaComm
family of high
performance clock products.
