Maximum frequency divider on Zmod DAC/ADC

[Zynq]

Hi we need to set the sampling rate for audio transmission through DAC and receiving through ADC, what is the maximum frequency divider that can be used? Is the original frequency 100M samples per second?

void ZMODDAC1411::setOutputSampleFrequencyDivider(uint16_t val)

Hi Zynq,

The max value is 0x3FFF. The function sets a 14-bit field of the Axi Adapter's control register. See the IP user guide for more info: https://github.com/Digilent/vivado-library/blob/zmod/v1/2019.1-2/ip/Zmods/AXI_Zmod_DAC1411/doc/ZmodDAC1411AxiAdapter.pdf

Yes, the sample rate for the DAC output should be 100 MS/s for any of the initially-released projects for Eclypse.

Thanks,

Arthur
