Intermodulation measured relative to either tone with analog input frequencies of 9.5 MHz and 9.9 MHz at 7 dB below full scale.
Power dissipation is measured at 30 MSPS with AIN of 10.3 MHz and digital outputs loaded with 10 pF maximum. See Figure 4 for power dissipation at other

*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum ratings for extended periods may effect device reliability.
