NB6L72MMNGEVB, 2x2 CrossPoint Switch Evaluation Board. The NB6L72M is a high-bandwidth fully differential 2 X 2 CrossPoint Switch with internal source termination and CML output structure, optimized for low skew and minimal jitter. The differential inputs incorporate internal 50 ohm termination resistors and will accept LVPECL, CML, LVDS, LVCMOS, or LVTTL logic levels. The SELECT inputs are single-ended and can be driven with LVCMOS/LVTTL. The 16mA differential CML outputs provide matching internal 50 ohm terminations and 400mV output swings when externally terminated with a 50 ohm resistor to VCC
