AMC3301: SNR and Clock rate

Part Number: AMC3301


Hi team,

Could you share more details on dv/dt spike noise, peak to peak noise and time domain noise waveform?

    Hi Ruixin,

    I'm not sure what you are looking for when you say you would like more detail on the 'dv/dt noise spike' of the AMC3301.  Is there are particular use case or operational mode you have in mind?  Figure 8-4 on page 24 of the datasheet shows the output transition in the case of a full scale (-250mV to +250mV) input step. 

    There are also various plots throughout the datasheet showing SNR data sweeps under various voltage/input/temperature conditions.  I'm afraid I don't understand the clock rate question - could you elaborate on that for me please?

    Hi Tom,

    Per talk with customer, the detail needs are as follows:

    1.Customer need 0.1Hz~10Hz time domain noise waveform.

    2. Customer think we can share noise results of  typical test condition like 10kV/us 400V step.

    3. Besides, do we have iso-amp which has higher oversampling freq, like 80MHz?

    Thanks!

    Hi Rayna,

    Please send me a note directly and we can chat about items 1 and 2.  At the moment, our modulators do not run at frequencies over 20MHz.
