Original question:

ADC34RF52: Difference between ADC34RF52 and ADC34RF55

ADC34RF52: ADC34RF52

Part Number: ADC34RF52
Other Parts Discussed in Thread: ADC34RF55

Tool/software:

Dear Team,

I understand that the ADC34RF55 has a maximum sampling rate of 3 GSPS. Could you please confirm whether this sampling rate is applicable to each individual channel, or is it a shared rate across all channels?

Thank you for your assistance.

    Hi Vamshi,

    All channels run at the same sample rate. To run the ADC34RF55 at max 3GSPS sample rate, some kind of decimation must be implemented due to exceeding output serdes rate max in bypass mode. To operate as quad channel ADC in DDC bypass mode, the max sample rate is 1.3GSPS for 14/16 bit (1x/2x avg) operation or 1.5GSPS for 12-bit operation.

    Thanks
