See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions.
2
Crosstalk is measured at 100 MHz with 1.0 dBFS on one channel and no input on the alternate channel.
3
Analog input bandwidth specifies the 3 dB input BW of the AD9644 input. The usable full-scale BW of the part with good performance is 250 MHz.
DIGITAL SPECIFICATIONS
AVDD = 1.8 V, DRVDD = 1.8 V, maximum sample rate, 1.75 V p-p differential input, VIN = 1.0 dBFS differential input, and DCS enabled,
unless otherwise noted.
