Determined by 3 dB reduction in reconstructed output at 75 MSPS.
Under normal operating conditions, the analog input voltages should not
exceed nominal 2 V operating range, nor the supply voltages (+V
whichever is smaller.
Under normal operating conditions the differential reference voltage may
range from 0.5 V to 2 V; +V

Absolute maximum ratings are limiting values, to be applied individually, and
beyond which serviceability of the circuit may be impaired. Functional oper-
ability under any of these conditions is not necessarily implied. Exposure to
absolute maximum rating conditions for extended periods may affect device
reliability.
Under normal operating conditions, the analog input voltages should not
exceed nominal +2 V operating range, nor the supply voltages (+V
whichever is smaller.
Under normal operating conditions the differential reference voltage may range
from 0.5 V to 2 V; +V
