(3) Evaluation of A/D using DIT at MCLK=384fs.
PORT1 (DIT) is used. On board DIT (AK4103) is set to the master mode. The AK4103 provides BICK and
LRCK to the AK5356 from an external master clock (MCLK). When using an external clock through a BNC
connector (J8), select “EXT” on JP11 (CLK) and short JP10 (XTE). (Refer to Table 2, Table 3 and Table 4 for
the set up of the DIP switches. The master mode should be selected in Table 2. The master clock (384fs) should
be selected in Table 4.)
