    I am thinking to use an AD633 in order to mix two digital frequencies. I have some questions regarding this device, is it possible to use this device for digital frequencies? I think it is but I wanted to ask to be sure and I don't know if someone could please tell me if by using the schematic in the datsheet for frequency multiplier it is possible to achieve the output with fc+fm fc and fc-fm.

    Thank you very much

    Help us out a bit - what are "digital frequencies'? Are the signals to mix pulses from logic IC's?

    well the digital frequencies ideally in my case should come from IC's however I am in the situation that I am going to have to use two signal generator TTL, for example 6.6 MHz and 6 MHz

    The AD633 is made for analog signal. It will not work very good for digital signal with a high selwrate. Look at figure 3 in the datasheet
