Hi Alberto,
My questions are :
1) Is that true ? In other words, are the ADC, DAC and FPGA clocks in the Mercury card all phase locked together ?
Yes, all the clocks are derived from the master 122.88MHz clock
2) If 1) is true, how should I behave when e.g. the input data have a sampling frequency of 96 kHz ? Should I send
an output frame every two input frames, or should I send the output frames at the same rates of the input ones,
repeating the data if need be ?
Always send the data at 48kHz, just discard data at higher rates.
Thanks
