Figure 25. Audio Data Interface Timing (Master Mode: BCK1/2 and LRCK1/2 work as Outputs)

The PCM3060 supports the following four interface formats in both slave and master modes, and they are

selectable independently for the ADC and DAC using serial mode control.

24-bit I2S format

24-bit left-justified format

24-bit right-justified format

16-bit right-justified format

All formats are provided in MSB-first, 2s complement data format.
