ADS54J42: "Fs/4 +/- Fin" Spurs and "Fs/2 - Fin" Spur

Part Number: ADS54J42

Hello,

My customer has a question.

[Q]

Is there a way to mitigate "Fs/4+/-Fin" spurs and "Fs/2-Fin" spur ?

[My understanding]

These are spurs caused by gain mismatch and phase mismatch, but I don't think there is a way to improve it on this device.

Best Regards,

Hiroshi Katsunaga
