New ContributorLatency of DE0-nano ADC
Hi, everyone, I am trying to use a DE0-nano for an application (I'm a beginner) and I was checking its ADC latency. I built a circuit that; in summary, reads the ADC value and echoes the binary code...

Frequent ContributorI did a quick check of the code. Since it's not using an on-chip ADC, the delay is unpredictable due to data transmission and communication overhead. If you want to accurately measure how fast the FPGA processes data internally, you can add SignalTap probes at the data input and output points and calculate the internal processing latency.

Hi,
to know about ADC128S022 latency, read the datasheet. You'll find that it's below 5 us at 3.2 MHz clock frequency and single channel operation. Everything else is software overhead.
