Changing ZMOD ADC sampling rate

[NithinA]

Hello,

Is there any way to control the sampling rate of the ZMOD ADC 1410 in a manner similar to the "frequencyDivider " parameter for the ZMOD DAC 1411 available in the ZMOD library?

Hi @NithinA

From software, short of decimating/averaging data captured at 100 MS/s down to some lower sample rate, there is not. It may be possible to reduce the clock frequencies in hardware, however we don't have an example or documentation detailing this, and the effectiveness of the calibration may be affected. The latest hardware-only demo release (https://digilent.com/reference/programmable-logic/eclypse-z7/demos/low-level-low-pass-filter) works with the ADC 1410 and runs it at 40 MS/s with a new release of the Zmod IPs, but these are incompatible with the currently-released AXI controllers.

Thanks,

Arthur
