DIR (COAX) (default) It is possible to evaluate the AK4388 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the received data through RCA connector (J3). Setting of jumper is shown below. COAX is recommended for an evaluation of the Sound quality. JP1 OPT COAX RX (Default) Figure 2. Jumper setting, when using DIR 2. DIR (Optical Link) It is possible to evaluate the AK4388 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the received data through optical connector (PORT3: TORX173).

(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. <KM083502> 23 2006/09 1 -15V +15V +5V VOP- VOP+ + C1 C2 470u R61 0 470u + T1 NJM78M05FA R62 NC NC 1 NC R28 NC IN OUT AVDD 2 R27 3 GND R26 R29 D3V 10k MCLK BICK LRCK SDATA 1 2 3 4 5 PORT2 10 9 8 7 6 R5,R8,R9,R10,C9 Setting for AK4384/4387/4388 #9 EXT R30 # 15 R5 NC C9 R10 R8 R9 AK4388 DIF1 DEM NC 0-ohm NC 0-ohm AK4387 NC DVDD 0-ohm 0.1u NC NC NC AK4384 P/S DZFR NC NC NC 0-ohm NC NC AVDD U1 R5 R6 4113_MCLK A 4113_BICK 4113_SDTO 4113_LRCK 5.1 MCLK 1 MCLK DZF 16 R2 100 BICK 2 BICK DEM 15 R3 100 SDTI1 3 SDTI VDD 14 R4 100 LRCK 4 LRCK VSS 13 RSTN 5 VCOM 12 C8 11 R57 RSTN A 6 SMUTE AOUTL 7 ACKS AOUTR 8 DIF0 + C6 0.1u 10u + RSTN NC 0 R1 C7 C20 R7 C9 10u NC NC NC NC 10 9 DIF1 AOUTL AK4388 C4 C5 10p NC AOUTR SMUTE D3V R11 10 8 6 4 2 PORT1 9 7 5 3 1 10k R12 10k R13 10k R14 R15 CSN CCLK CDTI R16 uP-I/F ACKS DIF0 P/S C36 0.1u 470 470 470 2 3 5 6 11 10 14 13 1 15 U4 1A 1B 2A 2B 3A 3B 4A 4B A/B G 1Y 4 2Y 7 3Y 9 4Y 12 VCC GND R25 AVDD R8 NC R9 0 R10 0 5.1 SW2 SW1 SMUTE P/S ACKS DIF0 16 8 1 2 3 4 8 7 6 5 DEM DIF1 1 2 3 4 8 7 6 5 SW DIP-4 SW DIP-4 74LVC157 SMUTE P/S ACKS DIF0 R17 R18 R19 R20 10k 10k 10k 10k R21 R22 R23 R24 10k 10k 10k 10k Title Size A3 Date: 1 AKD4388-SB Document Number Rev 1 AK4388 Tuesday, May 16, 2006 Sheet 1 of 3 1 C14 390p R47 C22 C24 100p NC R39 R41 3.9k 3.3k 0 VOP- 4 C45 NC C10 R35 R37 C16 910 22u 1.8k 3.9k NC 2 3 R33 22k C18 C12 8 + AOUTL 390p 100p R45 1 U3A NJM4580 C26 10u J1 MR-552LS 220 + R31 + 10u C29 + C28 0.1u - R58 NC 2 3 1 R43 20k R48 0 VOP+ R59 NC C30 0.1u C31 10u + C46 NC C15 390p A A C25 100p NC R40 R42 3.9k 3.3k 4 C23 R38 C17 1.8k 3.9k NC 6 5 8 + AOUTR C19 390p R34 22k R46 7 U3B NJM4580 C27 10u J2 MR-552LS 220 + R36 22u + C11 910 - R32 R44 2 3 1 20k C13 100p Title Size A3 Date: 1 AKD4388-SB Document Number Rev 1 Analog Tuesday, May 16, 2006 Sheet 2 of 3 1 S3 T2 uPC3533HF 1 VOP+ C32 47u + GND R56 IN OUT 3 OCKS1 OCKS0 H L 512fs@fs=32k/44.1k/48kHz L L 256fs@fs=88.2k/96kHz H H 128fs@fs=176.4k/192kHz Master Clock D3V 2 C33 0.1u 0 C34 0.1u SW3 1 2 AVDD SW4 RSTN D1 HSU119 1 2 3 L 2 OCKS1 OCKS0 R55 R54 10k 10k U2 R50 5.1 1 H C37 0.1u 4 3 OCKS R49 10k C38 10u + 1 DVDD CM0/CDTO/CAD1 30 2 DVSS CM1/CDTI/SDA 29 3 TVDD OCKS1/CCLK/SCL 28 4 V/TX OCKS0/CSN/CAD0 27 5 XTI MCKO1 26 6 XTO MCKO2 25 7 PDN DAUX 24 8 R BICK 23 4113_BICK 9 AVDD SDTO 22 4113_SDTO 10 AVSS LRCK 21 C39 0.1u C40 0.1u U5 1 2 3 4 5 6 7 1A 1Y 2A 2Y 3A 3Y GND VCC 6A 6Y 5A 5Y 4A 4Y 14 13 12 11 10 9 8 C35 0.1u 4113_MCLK 74HC14 A A R51 15k RSTN C47 NC R60 NC C41 10u + C42 0.1u 4113_LRCK INT0 J3 MR-552LS COAX C43 0.1u 2 3 1 11 RX1 INT0 20 12 RX2/DIF0 FS96/I2C 19 13 RX3/DIF1 P/SN 18 14 RX4/DIF2 INT1 17 15 RX5 RX6/IPS 16 COAX R52 75 JP1 RX OPT AK4113 PORT3 6 5 6 5 GND VCC GND OUT 4 3 2 1 C44 L1 0 0.1u 1 2 R53 100 TORX173 Title Size A3 Date: 1 AKD4388-SB Document Number Rev 1 DIR Tuesday, May 16, 2006 Sheet 3 of 3
