PCM4104, configured as fs=96kHz, TDM4, left-aligned, encountered a problem when debugging, the noise is normal, THD+N is very poor (the test point is the analog output pin of the chip):
1. When only CH1 and CH2 data are provided, the THD+N of CH1 can reach above -95dB, and that of CH2 can only reach about -80dB;
2. When all 4 channels provide data, the overall THD+N is very poor, about -78dB.
