See the AN-835 application note, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions and how these tests were completed.
2
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, 10.3 MHz sine input at rated sample rate.
4
Single data rate mode; this is the default mode of the AD9211.
5
Double data rate mode; user-programmable feature. See the Memory Map section.
