Thank you for the additional information. I am assuming that the crackling noise is seen at the input of the CODEC.

PLL review comments:
Page 0, R4 : PLL_CLK is input to CODEC_CLKIN, but there is no source selected for for PLL_CLK [D3:D2]
PLL Settings are; P=1, R=1, J=4, D=0
NDAC=1,MDAC=8,NADC=1,MADC=48,DOSR=192,AOSR=64. Is below expected settings?
TI has an online coefficient calculator to determine what values needed to program the programmable filter registers. Visit: https://www.ti.com/tool/COEFFICIENT-CALC and download the tool.
Plug in your values and click the Coeff button (bottom…
You may use the BQ calculation tool as below,
Also, below spreadsheet may help you to convert the dec numbers into 5.27 format or any format else.
1KHz sine wave passed through LPF of Fpass=12KHz and Fstop=17KHz (matlab generated coefficients) 64th order.
Signal length is fixed at 1024 and not (order+1)x4.
Radstep for 1KHz calculated by 1/2(sin(2*pi*i*k1) formula.

I'm looking for a polyphase version of the fir_f32.asm file provided as part of the C2000 libraries/source, i.e. where all samples are saved, but only the Nth output is calculated, for decimating a signal. I've attached my update, where the…
There is a dedicated high-pass filter option available and further filters can be designed using the Biquad filters. The attached tool aids in the design of these filters:
The TLV320AIC3206 contains several fixed function processing capabilities, including biquad filtering, which can be used for bass/mid/treble equalization.
There are biquads available both for the ADC and DAC stages and the configurations and…
