1 _{See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for definitions and for details on how these tests were completed.}
2 _{Crosstalk is measured at 10 MHz, with −1.0 dBFS analog input on one channel and no input on the adjacent channel.}
3 _{Overrange condition is defined as 3 dB above input full scale.}
