Evaluation Board For NB7L216 High Gain Differential Receiver/Driver

The NB7L216 is a differential receiver/driver with high gain output targeted for high frequency applications. The device is functionally equivalent to the NBSG16 but with much higher gain output. This highly versatile device provides 35 dB of gain up to 7 GHz.Inputs incorporate internal 50 O 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 pin is internally generated voltage supply available to this device only. The VBB is used as a reference voltage for single-ended NECL or PECL inputs. For all single-ended input conditions, the unused complementary differential input is connected to VBB as a switching reference voltage. VBB may also re bias AC coupled inputs. When used, decouple VBB via a 0.01 µF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB output should be left open.
