(1-2) A/D evaluation using DIT function of AK4114
Using X’tal (X2) and PORT2 (DIT). Nothing should be connected to J5 (EXT), J7 (RX), PORT1 (DIR), PORT5
(DIR) and PORT6 (ROM). Remove the X’tal (X1). JP6 (EXT) should be short. In normal speed and double speed
mode, JP1 (MCKO), JP4 (MCLK), JP5 (BCFS) and JP7 (LRFS) should be open.

• SW2 (MODE) setting (See Table 1)
Normal speed and double speed are same setting.
(1) Set the audio interface format of AK4114 using DIF2-0.
(2) Set the master clock output of AK4114using OCKS1-0.
(3) Set the PLL mode or X’tal mode of AK4114 using CM0.
(4) When XTALE is “H”, MCLK can output from MCKO1/2 pins though AK4584 is powered down.
(5) When DMCK is “H”, MCKO1 output is disabled.

Above figure is 24bit MSB justified, MCKO output of AK4114 is 256fs, AK4114 is X’tal mode.
Using DIT of AK4114, AK4114 is set X’tal mode.
