(1-1) Evaluation of Recording block (MIC, ADC) using DIT of AK4114
PORT2 (DIT) and X2 (X’tal) are used. DIT generates audio bi-phase signal from received data and which is
output through optical connector (TOTX141). Nothing should be connected to PORT1 (DIR) and PORT3
(Audio I/F), J12 (EXT). JP25 (EXT) is short. CM0 is set “H ” and CM1 is set “L ” for SW1, AK4114 is set X’tal
mode.

DIT does not operate under fs = 32kHz, this mode corresponds to fs = 32kHz and over.
(1-2) Evaluation of Playback block (HP, SPK, MOUT) using DIR of AK4114
PORT1 (DIR) is used. Nothing should be connected to PORT3 (Audio I/F) and J12 (EXT). X1 (X’tal) is
removed. JP25 (EXT) is short. CM0 is set “L ” and CM1 is set “L ” for SW1, AK4114 is set PLL mode.
