1 See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions.
2 Measurements made with a divide-by-4 clock rate to minimize the effects of clock jitter on the SNR performance.
3 Crosstalk is measured with a 170 MHz tone at −1 dBFS on one channel and no input on the alternate channel.
