Note 1. In case of using +5V power supply to connect VD, It is possible to supply the voltage to VD of AK5358B
without using Regulator(T1). In this case, JP3 is set to VD side.
Each supply line should be distributed from the power supply unit.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK5358B and AK4114 should be reset once bringing SW2 = “L” upon power-up.
„ Evaluation mode
(1) Slave Mode
(1-1) A/D evaluation using DIT function of AK4114
PORT2 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through
optical connector (TOTX141). It is possible to connect AKM’s D/A converter evaluation boards on the
digital-amplifier, which equips DIR input. Nothing should be connected to PORT1 (DSP).

(1-2) All interface signals including master clock are fed externally.
PORT1 (DSP) is used. All interface signals (MCLK, SCLK, LRCK) are provided to the AK5358B through
PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to “H”.
