AnyLevel™ Input to Open Collector CML Output Buffer/ Translator w/ Input Hysteresis

The NB4N316M is a differential Clock or Data receiver and will accept AnyLevel input signals: LVPECL, CML, LVCMOS, LVTTL, or LVDS. These signals will be translated to CML, operating up to 2.0 GHz or 2.5 Gb/s, respectively. As such, the NB4N316M is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock or Data distribution applications. The CML outputs are 16 mA open collector which require a resistor load path to VTT termination voltage. The open collector CML outputs must be terminated to VTT at power up. The differential outputs produce Current Mode Logic (CML) compatible levels when the receiver is loaded with 50-ohm or 25-ohm 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. The NB4N316M features an input threshold of approximately 25mV, providibg increased noise immunity and stability. The device is offered in a small 8-pin TSSOP package (MSOP-8 compatible).
