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. Default Setting +15V -15V Open Open 0V 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 <Default> 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 MCLK <KM082300> 2006/12 -2- ASAHI KASEI [AKD5386-B] Other jumper pins set up 1.

The function of the toggle SW Upper-side is “H” and lower-side is “L”. [SW2] (PDN): Resets of AK5386 and AK4114. Keep “H” during normal operation. AK5386 and AK4114 is reset by making SW1(PD) "L" once at the time of the power-up. Afterwards, please make SW1(PD) "H". <KM082300> 2006/12 -4- ASAHI KASEI [AKD5386-B] Analog Input Circuits Analog signal is input via J1(RIN) and J2(LIN) of RCA connectors.

(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. <KM082300> 2006/12 - 19 - A AGND2 J1 RIN E B 300 R19 51 300 -15V R13 300 R15 300 U4 AOUT +VP 8 2 -AIN BOUT 7 3 +AIN -BIN 6 4 -VP +BIN NJM4580 R20 AGND1 AGND2 R12 C31 2200p 5 C16 2200p R16 300 R14 300 U1 AGND1 R18 300 300 C2 10u GND C3 2.2u VA JP3 REG_VA 3 + C8 47u C5 10u VA VA + C4 0.1u C6 0.1u RP1 12 11 10 9 8 7 CKS0 CKS2 DIF0 DIF1 OCKS0 OCKS1 6 5 4 3 2 1 MODE 1k AINR CKS0 16 2 AINL CKS2 15 3 CKS1 DIF 14 4 VCOM PDN 13 5 AGND SCLK 12 SCLK 6 VA MCLK 11 MCLK 7 VD LRCK 10 D DIF0 REG C11 10u C9 0.1u 2 2 1 C7 0.1u OUT H + + C10 47u IN JP2 CKS1 SW1 1 + T1 NJM78M05DL1A 1 C L VA +15V 1 2 3 4 5 6 VD C1 10u +15V E DGND OCKS1 OCKS0 DIF1 + J2 LIN DGND 51 JP7 AGND D E JP8 GND 1 C13 2200p D AGND1 +15V R17 C30 2200p R11 C + C12 0.1u 8 DGND SDTO LRCK R5 9 51 C SDTO R7 0 AK5386 VD 2 VD R8 0 + C28 47u R6 10k D1 HSU119 REG 1 2 L 3.3V C29 0.1u SW2 PDN C14 0.1u 2 -15V 1 3 5 9 11 13 14 7 H 1 OUT JP4 REG_VD 3 C27 0.1u IN GND B 1 3 VD VD T2 LT1117-3.3 C15 0.1u 1A 2A 3A 4A 5A 6A VCC GND 1Y 2Y 3Y 4Y 5Y 6Y 2 4 6 8 10 12 B PDN 74HC14 2 -15V U2 C32 47u 1 + A A Title Size A3 Date: A B C D Document Number AKD5386-B AK5386 Thursday, September 21, 2006 Sheet E Rev 0 1 of 2 A B C D E DGND 3.3V + C17 10u E E PDN C18 0.1u OCKS1 OCKS0 IPS0 2 DIF1 36 NC OCKS0 35 3 DIF0 OCKS1 34 4 TEST2 CM1 33 5 DIF1 CM0 32 8 IPS1 XTO 29 BICK 26 12 VIN SDTO 25 3 2 GND 1 J3 TX T3 DA02-F 10 9 8 7 6 DSP X1 24.576MHz C C21 10p 24 23 DVSS 22 21 20 19 18 PORT1 C20 10p B + JP5 MCLK R9 240 A R10 150 Title Size A3 Date: A 1 2 3 4 5 BNC C26 0.1u 1:1 17 16 15 14 + IN VCC DIT A C25 10u JP6 TX OPT MCLK LRCK XTL1 MCKO1 11 DVDD 27 VOUT MCKO2 UOUT XTL0 COUT 10 BOUT 28 TX1 DAUX TX0 P/SN DVSS 9 C23 0.1u SCLK LRCK 1 XTI C22 0.1u 51 2 DIF2 C24 10u PORT2 31 30 13 B PDN 7 TVDD C 51 R4 MCLK SCLK LRCK SDTO SDTO AK4114 NC 51 R2 D U3 6 R1 INT1 AVDD 38 39 R 40 VCOM 42 41 AVSS NC RX0 43 44 RX1 45 TEST1 46 RX2 INT0 D DIF0 NC RX3 47 48 + 1 37 C19 0.47u B C D Document Number AKD5386-B Rev AK4114 Thursday, September 21, 2006 Sheet E 0 2 of 2
