This connector should be connected. And this connector is used when VA and VD of AK5386 is supplied from regulator T1 and T2. In this case, JP3 and JP4 should be REG side. When this is REG side, VA and VD connector should be open. (Default) This connector should be connected. This connector is used when VA of AK5386 is supplied from VA connector without regulator T1. In this case, JP3 should be VA side. This connector is used when VD of AK5386 is supplied from VD connector without regulator T2. In this case, JP4 should be VD side. This connector should be connected. This connector is used when DGND is supplied besides AGND. In this case, JP8 should be open.

Table 1. Power supply lines (Note) 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 AK5386 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
(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 AK5386 through PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to "H". JP5

JP3 (VA) : Select VA pin for AK5386 VA : Supply from VA connector. REG : Supply from regulator. In this case, VA connector should be open. 3. JP4 (VD) : Select VD pin for AK5386 VD : Supply from VD connector. REG : Supply from regulator. In this case, VD connector should be open. 4. JP5 (MCLK) : Select master clock of the AK5386. SHORT : AK4114 supplies MCLK. OPEN : PORT1 supplies MCLK. 5. JP6 (TX) : Select TX OPT : Optical Connector (PORT2) is used. BNC : BNC (J3) is used. 6. JP7 (AGND) : Analog ground 1 and Analog ground 2 SHORT : Common. OPEN : Separated. 7. JP8 (GND) : Analog ground 1 and Digital ground SHORT : Common. (The DGND connector can be open.) OPEN : Separated. In this case, DGND connector should be 0V.

(b) A critical component is one whose failure to function or perform may reasonably be expected to result, whether directly or indirectly, in the loss of the safety or effectiveness of the device or system containing it, and which must therefore meet very high standards of performance and reliability. * It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or otherwise places the product with a third party to notify that party in advance of the above content and conditions, and the buyer or distributor agrees to assume any and all responsibility and liability for and hold AKM harmless from any and all claims arising from the use of said product in the absence of such notification.
