ADS9110: Possible combination of zone 2 data transfer method (interleaving) and use of the 4 SDO lines ?

Part Number: ADS9110

Tool/software:

Hello,

I am looking for a ADC that is able to operate at 2MS/s but with the lowest possible clock frequency.

In my application, the signals are digitally isolated and a delay in the measurement is acceptable as the data are computed off line.

First, I have to choose between "Zone 1" and "Zone 2" for the data transfer configuration. The "Zone 2"  is obviously what I need. (figure 49 datasheet).

Because of the digital isolators and to get the lowest clock possible, I wish to use the 4 SDO lines to transfer the data in 5 clock times as in figures 78 or 80.

My question is : is it possible to use at the same time the "Zone2" data transfer method and the 4 SDO lines (combination of figure 49 and figure 78) ?

The documentation is not clear whether the combination is possible.

What would be in that case the lowest clock in "SDR" to operate at 2MS/s with the 4 SDO lines ?

Best regards,

François Wallart
