Figure 14 Left Justified Mode Timing Diagram

RIGHT JUSTIFIED MODE

In Right Justified mode, the LSB of input data is sampled on the rising edge of BCLK preceding a

LRCLK transition. The LSB of the output data changes on the falling edge of BCLK preceding a

LRCLK transition, and may be sampled on the next rising edge of BCLK. LRCLKs are high during the

left samples and low during the right samples.

2S MODE

In I2S mode, the MSB of DIN1/2/3/4 is sampled on the second rising edge of BCLK following a

LRCLK transition. The MSB of the output data changes on the first falling edge of BCLK following an

LRCLK transition, and may be sampled on the next rising edge of BCLK. LRCLKs are low during the

left samples and high during the right samples.
