ADS58J64: fNCO

Part Number: ADS58J64

Hello,

 

At ADS58J64, fNCO frequency is defined as follows.

           fNCO = NCO_WORD x fs / 2^16

What is fs here?

Is this fs the sampling frequency before the 1ts x2 decimation or the sampling frequency after x2 decimation?

 

Best regards,

 

K.Hirano

  • Fs is the sampling frequency before any decimation. --RJH

    RJH,

    Thank you for your response.

    Let me ask one more question.
    Is the NCO_WORD 2’s complement?

    Best regards,

    K.Hirano

    No. It is straight binary; no negative number. Reference section 7.4.1.1 in the datasheet and the register map. --RJH
