SSM3302 oscillator frequency

Hello ogura-san,

I will have to inquire about this further but I think there is not an easy answer. This part uses a spread spectrum sigma-delta modulator so I suspect the PDM modulation rate will change based on the input signals. Usually a PDM modulator will be 32 or 64x fs and possibly 128xfs but I am not sure and since the datasheet only mentions a spread spectrum feature and makes no mention about the PDM modulation rate I suspect this will be a proprietary detail that we may not want to disclose. 

What is the concern of the customer and have they evaluated the part? If we know more about the application we may be able to advise off of the forum.
