The NBSG16 is a differential receiver/driver targeted for high frequency applications. The device is functionally equivalent to the EP16 and LVEP16 devices with much higher bandwidth and lower EMI capabilities.Inputs incorporate internal 50-ohm termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), HSTL, LVTTL, LVCMOS, CML, or LVDS. Outputs are RSECL (Reduced Swing ECL), 400 mV.The VBB and VMM pins are internally generated voltage supplies available to this device only. The VBB is used as a reference voltage for single-ended NECL or PECL inputs and the VMM pin is used as a reference voltage for LVCMOS inputs. For all single-ended input conditions, the unused complementary differential input is connected to VBB or VMM as a switching reference voltage. VBB or VMM may also rebias AC coupled inputs. When used, decouple VBB and VMM via a 0.01 uF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB and VMM outputs should be left open.
