Hello,
looking at the adrv9009 datasheet and the profiles I have a doubt about the filter chain and the configuration in the device tree.
I have from the datasheet the next filter chain:
I have 2 half band filter, another with passtrought and then a filter FIR decimator.
with the profile configuration wizard i have the next response:
the generated profile inside the file there are filter coefs generated i assume for the last filter but looking at the coefs generated they have the next response:
also the decimation parameters are:
<rxFirDecimation=2>
<rxDec5Decimation=4>
<rhb1Decimation=2>
I'm not sure what i'm doing wrong or if I'm assuming not correclty the configuration or missing some info.
I have several doubts:
the chain in the datasheet is correct?. i have seen in other posts a different chain but i don't know where it come from:
what is the response of the others filters and how i can change it? if possible.
i would like at the end to use my own coefs at the device tree but i would like to understand first how the transceiver manage this vector of coefs.
regards.
