(B) ADC Evaluation of using internal DIT of AK4589
2-1. About analog inputs
2-1-1. BNC connectors J10 (LIN),J9 (RIN) are used for analog inputs.
2-2. About digital outputs (bi-phase outputs)
2-2-1. Optical connector PORT2 (TOTX176,TX1) or BNC connector J11 (TX1) are used for digital outputs.
2-2-2. .Select Optical connector PORT2 (TOTX176,TX1) or BNC Connecter J11 (TX1) for digital outputs
(bi-phase outputs) by JP2 (TX1)
Set JP2 (TX1) “OPT” side when Optical connector PORT2(TOTX176,TX1) is used for TX1 on
AKD4589-B.
Set JP2 (TX1) “BNC” side when BNC connector J11(TX1) is used for TX1 on AKD4589-B.
(See Figure3.)

2-2-3. Write (0,1) into (D5:CM1,D4:CM0) of addr00H:CLK & Power Down Control of control registers of
AK4589 (DIR/DIT) part (CM10=01:Clock Mode=X’tal Mode.)
Then clock source is X’tal (X1).
2-2-4. Set DIP-Switch SW2-2 (MASTER) ON.
Then mode is master mode.
Audio Digital Interface Format is 24bit left justified.
(Please refer to datasheet.).
(Default setting is master mode. Able to evaluate AK4589 on default setting.)
