Reduce latency of RF data converter.

Jump to solution

I'm using ZCU111 RFSoC evaluation board. I send data from DA and loop back to AD input at 4Gsps. There is latency of about 1000 samples between sending data and receiving data. How can I reduce latency?

Hi @makio999 

I'm afraid to say there is not much scope to do this effectively.

The latency through and ADC or DAC channel depends on how it is configured. 

Obviously bypassing the DUC/DDC will reduce latency but this is probably doesn't make sense if you need to do down conversion or upconversion with the mixer and decimation / interpolation
