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-ohm termination resistors and will accept LVPECL, CML, or LVDS logic levels. The 16 mA differential CML outputs provide matching internal 50 ohm terminations and produce 400 mV output swings when externally terminated with a 50 ohm resistor to VCC. The NB7V72M is the 1.8 V/2.5 V CML version of the NB7L72M and is offered in a low profile 3 x 3 mm 16-pin QFN package.
