Honored ContributorOkay, my project is to use 10MHz electronic signals as my information carrier.
1. I define that if I receive a 10MHz signal during a time period, then it is logic 1. If not, it is logic zero. 2. At the sending end, these logic 1s and 0s are sent by another board to drive a transducer to output the 10MHz electronic signal, through a complex channel, become a FM signal and finally it will be demodulated to a roughly 10MHz signal by FM demodulator. 3. At the receiver end, my idea is to use ADC to detect this roughly demodulated 10MHz electronic signal to digital data, for later FFT analysis. And I think 8-bit perhaps is enough (I'm not sure) for analysis because I have only to detect a single tone signal and it saves much space for storing. The receiver I choose is this FPGA (it is given by my supervisor actually) because it is fast. Later on this FPGA put all collected data to my computer and I do the analysis. 4. After the analysis, the last step is to compare the original digital data to my decoded data (10MHz is logic 1, no signal is 0)and gives the error bit rate. (I have another PFGA "spartan 3a Starter Kit" that has a build-in ADC but its sampling rate is only 1.5MHz. I'm trying to know whether it can work with an external ADC, the same question I ask here to find ADC to work with Cyclone IV) You told me to use JESD204, and I found this demo board, ADC1413D065W1. It seems it can meet my requirement. What do you think? Many thanks for your time
