About the data operation in internal DAC at Decimation
data per 4 periods of LRCK. Therefore, 1/2 decimation outputs a signal which has bandwidth until fs/2, and 1/4
decimation outputs a signal which has bandwidth until fs/4.
See the Figure 4. The 1/2 decimation takes in one data per 2 periods of LRCK, and the 1/4 decimation takes in one
