Jack Jack Voltage Names Colors Ranges Used for Comments and attentions Default Should be always connected. +15V VA (Note 1) Red +7V ∼ +15V VD Orange +2.7V ∼ +5.5V VD of AK5358B, 74HC14 Should be always connected. +5V VCC Green +3.0V ∼ +3.6V AK4114 Should be always connected. +3.3V AGND Black 0V Analog Ground Should be always connected. GND DGND Black 0V Digital Ground Should be always connected. GND ReguratorT1: VA of AK5358B Table 1. Set up the power supply lines. 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). JP5 MCLK Figure 2. Jumper setting, when using DIT function of AK4114 (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”. JP5 MCLK Figure 3.
