The NBSG16VS is a differential receiver/driver targeted for high frequency applications that require variable output swing. The device is functionally equivalent to the EP16VS device with much higher bandwidth and lower EMI capabilities. This device may be used for applications driving VCSEL lasers.Inputs incorporate internal 50-ohm termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), LVTTL, LVCMOS, CML, or LVDS. The output amplitude is varied by applying a voltageto the VCTRL input pin. Outputs are variable swing ECL from 100 mV to 750 mV amplitude, optimized for operation from VCC - VEE = 3.0 V to 3.465 V.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 single-ended input operation, 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 5F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB and VMM outputs should be left open.
