PLUTO sdr. Which part of the sdr system is implemented in FPGA?

greg@freshwaterbay.net on Jan 22, 2021

Is there any block diagram which shows what functionality in the signal processing chain is carried out in the FPGA? Thanks in advance.

Here is the closest diagram: https://wiki.analog.com/resources/eval/user-guides/ad-fmcomms2-ebz/reference_hdl

FMComms, ADRV936x, all share a similar structure if not identical.

By default, there is no DSP…

By default, there is no DSP applied to the datapaths for Pluto's RX and TX chains in the FPGA. However, you can enable extra decimate/interpolate by 8 in the data paths when using the DMAs. They are just inline with the DMAs and do not apply to the DDS path.
