See the
Application Note,
Understanding High Speed ADC Testing and Evaluation,
for a complete set of definitions and how these tests were completed.
The input range is programmable through the SPI, and the range specified reflects the nominal values of each setting. See the Memory Map section.

I
AVDD
and I
DRVDD
are measured with a −1 dBFS, 30.3 MHz sine input at rated sample rate.
4
Single data rate mode; this is the default mode of the AD9434.
5
Double data rate mode; user-programmable feature. See the Memory Map section.
