Description
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  termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), LVTTL, LVCMOS, CML, or LVDS. The output amplitude is varied by applying a voltage to 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.
