    Hello,

    I'm new to ADC/DAC world but has been reading up a lot on them lately. However one thing is still confusing that is how to calculate the range of a clock input to the ADC from a given spec like a sampling rate of 1.25Mbps. What is the formula to calculate it? It seems to me that another given spec like N bits is also needed.

    Thanks

    It depends entirely on the type of ADC. There's no one rule for determining the clock rate from the sample rate. You need to look at the data sheet for the ADC you are using.

    When you figure something out it is nice to know what you figured out. It might help someone else.

    Sharing information is what AAC is all about.
