■ TDM Cascade Mode
The AK4618 can be connected with other ADCs or CODECs in cascades in TDM mode. In Figure 32, the SDTO pin of
ADC or CODEC is connected with the TDMI pin of the AK4618. TDMI data is added after the 6channel ADC data of
SDTO1.It is possible to output 8channel TDM data from the SDTO1 pin of the AK4618 as shown in Figure 22 ~ Figure
26 in TDM256 mode, and it is possible to output 16channel TDM data as shown Figure 17 ~ Figure 21 in TDM512 mode.
