As the maximum sampling frequency that i can use to sample data from IQ chain is 61.44MSPS..my question is what is there any step size for changing the frequency rate.. or can i take any number ?
Sampling rate depends on the input signal, for example LTE 20MHz has a datarate of 30.72 MSPS . You can configured required sampling rate between 61.44MSPS and 520.833KSPS .
Please use filter Wizard to configure the digital path.
