ASAHI KASEI [AKD4370-A] AKD4370-B Evaluation Board Rev.0 for AK4370 GENERAL DESCRIPTION The AKD4370 is an evaluation board for 24bit DAC with Headphone Amplifier, AK4370. The AKD 4370 has the interface with AKM’s ADC evaluation boards. Therefore, it’s easy to evaluate the AK4370. The ADK4370 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD4370-B --- Evaluation board for AK4370 (Cable for connecting with printer port of IBM-AT compatible PC and control software are packed with this. This control software does not operate on Windows NT.) FUNCTION • Compatible with 2 types of interface - Direct interface with AKM’s A/D converter evaluation boards - On-board AK4116 as DIR which accepts optical input • 10pin header for serial control interface • Mini-jack for external Stereo Speaker • On-board Class-D Speaker Amplifier (AK7832) Vcc (5.0V) GND Regulator (3.3V) Opt In (PORT1) HPL AK4116 (DIR) DSP 10pin Header (PORT2) HPR AK4370 SPPL AK7832 (SPK-Amp) Control Data 10pin Header (PORT3) LIN1 RIN1 LIN2 RIN2 HP SPPR LOUT ROUT L/ROUT Figure 1.

[VCC] (red) = 5.0V : for Regulator [AGND] (black) = 0V : for analog ground [DGND] (black) = 0V : for logic ground Each supply line should be distributed from the power supply unit. 3.3V is supplied to via the regulator. 2) Set up the evaluation mode, jumper pins. (See the followings.) 3) Power on. The AK4370 and AK4116 should be resets once bringing SW1 (DAC/DIR_PDN) “L” upon power-up. And the AK7832 should be resets once bringing SW2 (SPK_PDN) “L” upon power-up. Evaluation mode When evaluating the AK4370 using the PORT1(AK4116), it is possible to use the initial setting of the audio interface format (24bit MSB justified). The AK4116 operates at fs of 32kHz or more. If the fs is slower than 32kHz, any other evaluation mode should be used. When inputting the data from the PORT2, the AK4370’s audio interface format should be set to correspond the input data’s audio interface format. Refer to the AK4370’s datasheet.

(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. <KM086300> 2006/12 - 23 - D E RIN2 LIN1 C LIN2 B RIN1 A DGND JP1 GND AGND E E HPL 19 20 HPR HPL 21 RIN2 SDATA VSS1 18 2 BICK HVDD 17 C1 0.1u 51 BICK D 2.2u C6 14 ROUT VSS2 LOUT 13 LOUT 12 I2C MUTET ROUT 11 6 AVDD_REG C5 0.1u DVDD PDN 5 C9 0.1u 16 15 10 10u C8 D C4 10u VCOM 7 + MCKI CSN/CAD0 DVDD 4 9 10 AVDD AK4370VN CCLK/SCL R5 MCKI LRCK 8 LRCK CDTI/SDA 3 51 HVDD_REG C3 0.1u 51 R4 C2 10u + R3 22 1 + R2 RIN1 51 SDATA + R1 LIN2 24 LIN1 U1 23 HPR JP11 INLN JP12 INRN C13 0.1u C15 0.1u B4 B5 NC INRN INLP A5 B1 A3 INLN B3 NC INRP U2 SCL B2 + R7 51 A1 C 1u C14 A2 C NC E5 VSS3 VCLP E4 VCLP VC VSS1 E3 VCLN VCRP E2 PDN CSN CCLK CDTI C16 C17 0.1u C1 B AK7832 0.01u DVDDI B JP2 VDD1 D5 D4 D3 D2 D1 C4 VCLN PDN VSS2 C3 I2CEN SPK_PDN C5 R8 47k VCRN NC I2C_SEL VDD2 SDA E1 VDD3 C2 VCRP VCRN D_REG A A Title Size A3 Date: A B C D AKD4370-B Document Number Rev AK4370 , AK7832 Monday, October 30, 2006 Sheet E 1 of 0 3 A B C D E D_REG LIN1 DIR_REG 2 2 AVDD_REG JP13 C21 1u J3 LIN2/RIN2 RIN2 6 DVDD DVDD_REG C27 1u 4 3 C30 1u R12 47k LIN2 D R11 220 ROUT + + C26 47u HP HVDD_REG + GND 1 C24 0.1u R10(short) 4 3 HPL L4 (short) OUT C23 0.1u J4 + IN 1 C28 100u 6 L3 (short) T1 TA48M33F + C22 47u 2 C20 1u 4 3 C25 100u HPR + 1 RIN1 6 2 L2 (short) R9 (short) + 1 C19 1u J2 LIN1/RIN1 L1 10u + E VCC +5V + E D J6 + 6 C32 1u R13 220 4 3 LOUT L/R OUT R14 47k TP2 VCLN J7 6 1 VCLN TP3 VCLP C C 1 VCLP 4 3 SPP_L TP4 VCRN J8 6 1 VCRN TP5 VCRP 1 VCRP 4 3 SPP_R B B A A Title Size A3 Date: A B C D AKD4370-B Document Number Rev Input/Output Monday, October 30, 2006 Sheet E 0 2 of 3 A B C D E E E D_REG D_REG R15 1k K 2 A PORT1 C34 0.1u PDN TORX141 C35 0.1u C36 10u D 14 Vcc 7 4Y 4A 5Y 5A 6Y 6A 8 9 10 11 12 13 SPK_PDN GND U3 74HC14 D1 HSU119 L 1 H 3 L R19 12k C39 0.1u 16 INT0 17 PDN 18 AVSS R D R17 10k H C38 SW2 0.1u SPK_PDN 2 SW1 DAC/DIR_PDN 19 20 AVDD U4 D2 HSU119 A C37 0.1u R18 470 R16 10k A + DIR_REG 3 2 1 1A 1Y 2A 2Y 3A 3Y 2 GND OUT 1 2 3 4 5 6 K VCC 3 K LED1 ERF L5 47u 1 1 C33 0.1u 1 RX0 INT1 2 DVDD CSN 15 14 CSN CCLK 13 CCLK CDTI 12 CDTI R20 5.1 DIR_REG TP6 XTI 3 DVSS 4 XTI AK4116 U5 C X1 11.2896MHz 11 3 A1 B1 21 4 A2 B2 20 PDN CDTO MCKO DAUX SDATA JP3 LRCK2 5 A3 B3 19 6 A4 B4 18 7 A5 B5 17 MCKI 8 A6 B6 16 CSN 9 A7 B7 15 CCLK 10 A8 B8 14 10 9 6 SDTO CDTO BICK XTO 8 5 LRCK 2 C43 10p C41 0.1u 7 C42 10p C 10u C40 1 1 + LRCK JP4 BICK2 BICK JP5 MCLK JP6 BICK JP7 LRCK B B JP8 SDTO D_REG C44 0.1u 1 VCCA VCCB 24 2 DIR VCCB 23 11 GND OE 22 12 GND GND 13 PORT2 MCLK BICK LRCK SDTI 1 2 3 4 5 10 9 8 7 6 GND GND D_REG R21 10k R22 470 R23 10k R24 470 R25 10k R26 470 DVDD C45 0.1u DSP 74AVC8T245 D_REG R27 10k PORT3 1 2 3 4 5 A 10 9 8 7 6 uP-I/F CSN SCL/CCLK SDA/CDTI CDTO CDTI CDTO JP9 SDA A JP10 CAD0 Title Size A2 Date: A B C D AKD4370-B Document Number Rev CLOCK Thursday, November 16, 2006 E Sheet 0 3 of 3
