After a lot of research, i've narowed down my choice of components to an AD8131 to convert my singe ended signal to differential ended, and the AD9461 to perform the high speed conversion.
Now, i just a have some doubts around the "common mode…
We are designing DDC receiver (decided to use AD9461) .
We must provide sensitivity above -120dBm (10 dB SNR / bandwidth 12kHz). To simplify the calculations I take unmodulated carrier.
My preliminary calculations are:
AD9461 SNR = 77 dBF…
Are you providing a valid clock to the AD9461? Are you checking the DCO using a scope?
I am working on the RF receiving coil of MRI scanner, and a magnetic compatible low noise amplifier is required to work as pre-amplifier inside the magnetic body. The magnetic field could be 1.5T or maybe up to 7T. I noticed that ADI has a document…
I have some question on determining the IF sampling capability of ADC's :
I've checked the ADCs selection table for ADC > 10MSPS
