Engineer Zone:

 

  If you have configured the ADC and DAC sampling rates to the same frequency, is it necessary to use a fifo to buffer the samples between the ADC and the DAC. In this case connecting the AD9643 PCORE ADC LVDS INTERFACE to the AD9122 PCORE DAC LVDS INTERFACE?

In know there could be some jitter. But for a simple loopback it seems like it would be ok?

 

 

Thanks,
