PCM3168A: In I2S master mode, are the two LRCK outputs in phase?

Stephen Gordon

Part Number: PCM3168A

When running ADCs and DACs in I2S master mode and interfacing both to the same slave system, can we assume that LRCKAD and LRCKDA output are in phase, and therefore only connect one of them to the slave system?

Hi Stephen,

Thanks for your patience. Assuming that both ADC/DAC have the same audio data format, yes then both clocks will be in phase according to Figures 4, 5, and 6 in the datasheet.

Best regards,
