I have two questions according to the clocking options/recommendations for the PCM5141
Under 22.214.171.124, the datasheets it says:
"In situations where the highest audio performance is required, it is suggested that the SCK is brought to the device, along with BCK and LRCK".
Can someone explains, why SCK AND BCK/LRCK should be provided externally? As far as I understand the jitter that has impact on the audio signal is the jitter present in the SCK signal (and only the SCK signal?), because the output DACS operate on this frequency. Does the internal derivation of BCK and LRCK from the externally provided SCK really have an inpact on audio performance?
Related to 1.): Assume that I can NOT follow the recommendations in 1.) by providing ALL of the three signals (SCK, BCK and LRCK) externally, what is the next best option to go concerning audio quality? I would assume it is the variant described in 126.96.36.199 Clock Master Mode from Audio Rate Master Clock. I would think so because of my thoughts in 1.). Can you tell me whether this is correct?
Thanks a lot
