Other Parts Discussed in Thread: TAS5825M
Dear TI Team,
I have questions about understanding the sample rate and DRC on the TAS5825M. We feed the TAS with variable sample rates up to 44.1kHz, 48kHz, 88.2kHz and 96kHz. Our test setup is a PurePath Console motherboard equipped with a TAS5825EVM. Among other things a 3-band EQ is programmed (on a 48kHz process-flow). Basically everything works. What would be the optimal setting for the parameters in the field Sample Rate Conversion (Base Sample Rate and Input Sample Rate) and for the register bits FSMODE? If the Base Sampling Rate is the rate at which the coefficients are calculated, why should the FSMODE bits be set manually for e.g. 44.1kHz? If the Base Sampling Rate is set to As Input, why is the Input Sampling Rate only displayed as 48kHz?
How do the above settings affect the EQ coefficients? Are they changed in the generated header file according to what?
Many thanks and best regards
