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 3 dB above the full-scale input range.
4
PSRR is measured by injecting a sinusoidal signal at 10 MHz to the power supply pin and measuring the output spur on the FFT. PSRR is calculated as the ratio of the
amplitudes of the spur voltage over the pin voltage, expressed in decibels.
DIGITAL SPECIFICATIONS
AVDD = 1.8 V, DRVDD = 1.8 V, 2 V p-p differential input, 1.0 V internal reference, AIN = 1.0 dBFS, unless otherwise noted.
