I'm using this design example to find the frequency present at RX path using FFT.I'm using default HB filter configuration with no FIR filter.
What i noticed is that maximum data rate that i could have in HDL RX path is 61.44Mhz which is also confirmed by UG-570 guide. This also limits the maximum real-time frequency that can be calculated in RX path. If i want to use 1RXTX mode of ad9361, is it possible to have more than 61.4Mhz data rate? Like bypassing HB filters? Because RX path after the adc_axis_fifo is running at 100Mhz. Just wanted to confirm these facts before moving forward in my project.
The maximum data rate is 61.44 MSPS, even if 1RX1TX is used. The analog bandwidth is limited to 56 MHz.
I have few more questions related to this thread.
Regarding 1, please see https://ez.analog.com/wide-band-rf-transceivers/design-support/f/q-a/111779/maximum-bandwidth-and-maximum-sample-rate
2. I don't remember a specific reason for this rate when the project was created. Possibly to be a good rate for LTE.
