1-1. About digital inputs (bi-phase inputs)
1-1-1. Optical connector PORT3 (TORX176,RX0) or BNC connector J12(RX0) are used for digital
inputs(bi-phase inputs) .
1-1-2.
Select Optical connector PORT3 (TORX176,RX0) or BNC Connector J12(RX0) for digital inputs
(bi-phase inputs) by JP3 (RX0)
Set JP3(RX0) “OPT” side when Optical connector PORT3(TORX176,RX0) is used for RX0 on
AKD4589-B.
Set JP3(RX0) “BNC” side when BNC connector J12(RX0) is used for RX0 on AKD4589-B.

1-1-3.
Write (0,0) into (D5:CM1,D4:CM0) of addr00H:CLK & Power Down Control of control registers of
AK4589 (DIR/DIT) part (CM10=00:Clock Mode=PLL Mode.)
Then clock source is PLL.
(Default setting is PLL. Able to evaluate AK4589 on default setting.)
1-1-4.
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.)
1-2. About analog outputs
1-2-1. BNC connector J2 (LOUT1), J1 (ROUT1), J4 (LOUT2), J3 (ROUT3), J6 (LOUT3), J5 (ROUT3),
J8 (LOUT), J7 (ROUT4) are used for analog outputs.
