KM34 AFE decimation filter

[Bnu]

Hello

I am working on AFE where there are settings for decimation filter, OSR, etc can anyone help me out with the bandwidth, modulator frequency or other calculations within this module. I cannot find anything regarding this.

Thanks in advance.

Hello @Bnu,

Could you please check the Kinetis KM34 Sub-Family Reference Manual? In Chapter 31. Analog Front End (AFE) there is a section of OSR (Section 31.6. OSR Select) and Decimation Filter (Section 31.11. Decimation Filter) that might be useful to look at.

Also, it might be useful to take a look at the following information:

• Filter-Based Algorithm for Metering Applications
• AFE (Analog Front End) KM-Family - Questions - NXP Community

Best regards, Raul.
