Hi ADI Engineer
I cant find the resolution well defined for ADC in AD9371. 16bit
or 12bit. Note that the ADC that used to RX1 AND RX2 rather than AUXADC.
It is defined in JESD parameter table.
Thank you for your answer.
I kenw the table before. But the SNR is defined about 60db(specific of the SNR as follow picture). If we define N as 16 in JESD parameter, the SNR should be more more than 60db,right?
I want konw whether the number of resolution bits is already extended after the LPF.
yes as the ADC is sigma delta architecture the resolution is extended after LPF.
So how can i find the resolution of ADC before LPF in ad9371?
Can you let us know the reason you are looking for this parameter.
i want to estimate the rx link gain for my system design but before that i need to know the ADC Quantify noise and than i can know how much amplification should be set.
The ADC Quantify noise relay on the resolution of ADC in the past design.
Can you please take a look at below App note . Hope this helps.
We do not have data for SNR and SFDR or ADC. Primary reason bring since it is integrated transceiver the spurs seen are not just because of ADC but due to other components in the signal chain as well and these vary with LO frequency, Sampling rate, device clock rate etc . Also a single value doesn’t hold good for different configurations.
We recommend customers to test for their band of frequency and profile , and observe the resulting spurs for a specific use case.
