The PCM5310 supports I2S, left-justified, and right-justified data formats with 32 fS, 48 fS, or 64 fS BCK rates for
digital input, and 48 fS or 64 fS BCK rates for the ADC. The data formats are shown in Figure 34 and can be
selected through the I2C interface. All formats require binary twos complement, MSB first audio data. The default
format is 16- to 24-bits I2S. Figure 35 and Figure 36 show detailed timing diagrams. The descriptions for the
audio interface data format registers are shown in Table 11.
