ADC12J4000 Data Output Format

Other Parts Discussed in Thread: ADC12J4000

Hi, i'm reading the datasheet of ADC12J4000 and I would to know how the samples are formatted between lanes, without decimation.

At the page 40 there are 2 tables about this. The first has L=8 M=8 F=8 and I if understood it, so I have the same sample on 8 "differents" ADCs at the same time, right?

In the 2th table, there's "Composite View of Interleaved Converters" and so I have 8 consecutive samples on 8 Interleaved ADCs at the same time, right?

How can i select the "Interleaved Mode"?

Thanks

Didn't I understand it? Maybe the 2 tables are the same, and it's just a different view of samples?

Hi s c

Yes, the two tables are two different ways of looking at the same formatting mode.

The first table shows how we meet the constraints of the JESD204B standard. The second one shows how to consider the samples for the single ADC case (interleaving the 8 sub-converters needed to comply with the standard).

I hope this is clear.
