NB4N11MDTEVB

The NB4N11M is a differential 1-to-2 clock/data distribution/translation chip with CML output structure, targeted for high-speed clock/data applications. The device is functionally equivalent to the EP11, LVEP11, SG11 or 7L11M devices. The device produces two identical differential output copies of clock or data signal operating up to 2.5 GHz or 2.5 Gb/s, respectively. As such, NB4N11M is ideal for SONET, GigE, Fiber Channel, Backplane and other clock/data distribution applications.Inputs accept LVPECL, CML, LVCMOS, LVTTL, or LVDS. The CML outputs are 16 mA open collector which requires resistor (R) load path to VTT termination voltage. The open collector CML outputs must be terminated to VTT at power up. Differential outputs produces current mode logic (CML) compatible levels when receiver loaded with 50 O or 25 O loads connected to 1.8 V, 2.5 V or 3.3 V supplies. This simplifies device interface by eliminating a need for coupling capacitors.
