7.3.8.6.5 DIR Data Description
Decoded Serial Audio Data Output and Interface Format
The PCM9211 supports the following four data formats for the decoded data:
- 16-bit MSB First, Right-Justified
- 24-bit MSB First, Right-Justified
- 24-bit MSB First, Left-Justified
- 24-bit MSB First, I2S
Decoded data are MSB first and twos complement in all formats.
The format of the decoded data is selected by the RXFMT[2:0] register. Table 7-7 lists the possible data formats.
Table 7-7 DIR Serial Audio Data Output
Format Set by RXFMT[2:0]
| DIR SERIAL AUDIO DATA OUTPUT FORMAT | RXFMT[2:0] SETTING | ||
|---|---|---|---|
| RXFMT2 | RXFMT1 | RXFMT0 | |
| 24-bit MSB First, Right-Justified | 0 | 0 | 0 |
| 16-bit MSB First, Right-Justified | 0 | 1 | 1 |
| 24-bit MSB First, I2S (Default) | 1 | 0 | 0 |
| 24-bit MSB First, Left-Justified | 1 | 0 | 1 |
Figure 7-12 depicts the latency time between the input biphase signal and LRCKO/DOUT. Figure 7-13 illustrates the DIR decoded audio data output timing. Section 6.8 lists the timing requirements.
