Adar7251 maximum sampling rate?

Hello,

 

In the datasheet of the adar7251 on page 26 it is mentioned that sample rate, in ADC PPI Byte Wide mode, can be increased up to 3.6MHz, by limiting ADC resolution to 11 bits.

Has this been tested, because in register it states that maximum is 1.8MHz and two configurations above 1.8MHz are reserved?

Also, what is the data format of those 11 bits? Are they also in twos complement?

What is in upper 5 bits?

 

Thanks in advance.

 

Best regards,

Nenad
