        1. 2.1.2.1 Supported Sample-Rates
        2. 2.1.2.2 Example
  5. 3Edge Sync for I2S and LJF in Controller Mode
    1. 3.1 Compatibility With Non-zero Offset
    2. 3.2 I2S Compatibility With Zero Offset (I2S only)

2.1.2.1 Supported Sample-Rates

Table 2-6 shows the supported sample-rates with the PLL disabled. As shown in Table 2-6, higher MCLK ratios allow the use of greater number or greater computation of digital processing blocks due to the greater availability of clocks in the system.
