NB7L216
2.5V/3.3V, 12Gb/s Multi
Level Clock/Data Input to
RSECL, High Gain
Receiver/Buffer/Translator
with Internal Termination
Description
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 W termination resistors and accept
Negative ECL (NECL), Positive ECL (PECL), LVTTL, LVCMOS,
CML, or LVDS. Outputs are Reduced Swing ECL (RSECL), 400 mV.
The VBB pin is an internally generated voltage supply available to
this device only. 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 should be connected to VBB
as a switching reference voltage. VBB may also rebias AC coupled
inputs. When used, decouple VBB via a 0.01 mF capacitor and limit
current sourcing or sinking to 0.5 mA. When not used, VBB output
should be left open.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared operating
temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values
are applied individually under normal operating conditions and not valid simultaneously.
12. Measured by forcing VINPPmin from a 50% duty cycle clock source. All loading with an external RL = 50 W to VTT =VCC − 2.0 V. Input edge
rates 40 ps (20% − 80%).
13. Duty cycle skew is measured between differential outputs using the deviations of the sum of Tpw− and Tpw+ @ 1 GHz.
14. VINPP (MAX) cannot exceed VCC − VEE. Input voltage swing is a single−ended measurement operating in differential mode.
15. Additive RMS jitter with 50% duty cycle clock signal.
16. Additive peak−to−peak data dependent jitter with input NRZ data at PRBS 223−1.
17. Device to device skew is measured between outputs under identical transition @ 1 GHz.
