Production Data

PD, August 2013, Rev 4.2

Figure 28 I

2S Justified Audio Interface (assuming n-bit word length)

In DSP/PCM mode, the left channel MSB is available on either the 1

st (mode B) or 2nd (mode A) rising

edge of BCLK (selectable by LRP) following a rising edge of LRC. Right channel data immediately

follows left channel data. Depending on word length, BCLK frequency and sample rate, there may be

unused BCLK cycles between the LSB of the right channel data and the next sample.

In device master mode, the LRC output will resemble the frame pulse shown in Figure 29 and Figure

30. In device slave mode, Figure 31 and Figure 32, it is possible to use any length of frame pulse less

than 1/fs, providing the falling edge of the frame pulse occurs greater than one BCLK period before

the rising edge of the next frame pulse.
