(6)
For Fs > 105 MSPS, it is recommended to use external clock for data capture and NOT the device output clock signal
(ADC_DCLKOUT).
(7)
For Fs > 65MSPS, CMOS output buffers strength is increased by writing serial register bits STR_CTRL<1:0> = '10'.
(8)
Data valid refers to LOGIC HIGH of 1.26 V and LOGIC LOW of 0.54 V.
