ADS5562: Input power in dBm of differential pin of device.

Part Number: ADS5562

Hi,

I'm going to develop by using ADS5562 AD converter.

In this time, I want to know the following items.;

   1) how much is Input power in dBm of differential input port? I designed the method inputted by single-ended signal as evalution board circuit using two transformer.

    

   2) how much is the clock reference signal(pin-10, CLKP) by CMOS input condition?

    Jarden,

    I do not understand your first question. No matter what your input power is in dBm, just make sure the voltage on each analog input pin is VCM +/- 0.9V. This should be 0.6V to 2.4V.

    For the second question, this should be at least 0.4V and no greater than 3.9V.

    Regards,

    Jim

    Hi Jim,

    My question_1) means that I want to know what is input power of ADS5562.
    ; 1) how much is Input power in dBm of differential input port? I designed the method inputted by single-ended signal as evalution board circuit using two transformer.

    Jaden,

    Are you saying your board has the same analog front end circuit as the ADS5562EVM and you want to know how much signal amplitude you can use on the single-ended input and stay within specification of the ADC?
