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

No missing codes guaranteed if Register 0x18 = 0x04 (default, no digital scaling of the output).

3

Measured with a low input frequency, −1 dBFS sine wave on both channels, DDR operation, and two-lane operation.

4

Standby mode can be controlled via the SPI.
