ASAHI KASEI [AKD4642EN-B] AKD4642EN-B AK4642EN Evaluation board Rev.0 GENERAL DESCRIPTION AKD4642EN-B is an evaluation board for the AK4642EN, 16bit CODEC with built-in MIC/HP/SPK amplifier. The AKD4642EN can evaluate A/D converter and D/A converter separately in addition to loop-back mode (A/D → D/A). The AKD4642EN also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD4642EN-B --- Evaluation board for AK4642EN (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.)

Evaluation Board Manual Operation sequence 1) Set up the power supply lines. [VCC] (red) = 5.0V [AGND] (black) = 0V [DGND] (black) = 0V : for logic : for analog ground : for logic ground Each supply line should be distributed from the power supply unit. 3.3V is supplied to AK4642EN and AK4114 via the regulator. 2) Set up the evaluation mode, jumper pins. (See the followings.) 3) Power on. The AK4642EN and AK4114 should be reset once bringing SW1 “L” upon power-up. Evaluation mode (1) Slave mode (1-1) Evaluation of Recording block (MIC, ADC) using DIT of AK4114 (1-2) Evaluation of Playback block (HP, SPK, LOUT) using DIR of AK4114 (1-3) Evaluation of Loop-back using AK4114 <Default> (1-4) All interface signals including master clock are fed externally. The AK4114’s audio interface format is fixed to I2S compatible. (1-1) Evaluation of Loop-back using DIT of AK4114 PORT2 (DIT) and X1 (X’tal) are used.

(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. <KM079300> 2005/06 - 26 - A B C D E JP1 GND DGND E ROUT AGND T45_B T45_B 1 DGND T45_R 1 VCC 1 LOUT BEEP RIN2 LIN2 LIN1 RIN1 E AGND VCC + C1 1u MPWR + REG + C6 10u JP13 I2C_SEL C10 4.7n C 25 MUTET ROUT 26 27 LOUT RIN2 BEEP 29 30 IN1- 1 MPWR HPL 24 HPL 2 VCOM HPR 23 HPR 3 AVSS HVSS 22 4 AVDD HVDD 21 C5 0.1u C7 0.1u R3 C8 0.1u 4642EN 10k 5 VCOC 6 I2C 7 PDN + C4 2.2u LIN2 32 IN1+ U5 28 D 31 D C9 10u JP12 HVDD PIEZO VCC Dynamic REG C SPP 20 SPP SPN 19 SPN MCKO 18 TEST2 MCKI 17 MCKI R4 47k 51 DVSS 16 15 14 BICK LRCK 13 10 9 DVDD CSN/CAD0 SDTO 8 12 51 SDTI R7 CSN 11 PDN CDTI/SDA R6 CCLK/SCL R5 10 C11 0.1u B R9 51 R10 51 R11 51 R12 51 B R13 51 BICK LRCK SDTO SDTI CDTI CCLK + R8 51 C12 10u A A Title Size A3 Date: A B C D AKD4642EN-B Document Number Rev AK4642EN Friday, June 10, 2005 Sheet E 0 1 of 5 A B C D C15 47u + R16 6.8 6 HPR C14 1u 6 BEEP + 4 3 R15 20k C19 1u 6 E HPL C13 47u J3 LIN2/RIN2 J1 HP 4 3 + E J2 BEEP E C16 0.22u C17 0.22u R17 10 R18 10 R14 6.8 + RIN2 4 3 D D C18 1u + LIN2 R1 2.2k R19 10 MPWR 3 4 SPP J4 SPK-JACK 6 R2 2.2k SPK1 D1 A J5 LIN1/RIN1 C JP3 RIN1 6 C3 1u Piezo(EXT) Dynamic K DIODE ZENER + RIN1 JP5 SPKP D2 4 3 A C2 1u + JP2 LIN1 020S16 CN1 K DIODE ZENER P 2 C Dynamic Piezo(EXT) 1 JP4 SPKN N LIN1 SPN R20 10 C21 1u R23 220 + B B J6 LOUT/ROUT 6 ROUT R24 20k C20 1u 4 3 + R21 220 LOUT R22 20k A A Title Size A3 Date: A B C D AKD4642EN-B Document Number Rev Input/Output Friday, June 10, 2005 Sheet E 0 2 of 5 A B C D E VCC REG 1 VCC L1 47u T1 TA48033F GND OUT 2 1 TORX141 C27 10u + C29 10u C28 0.1u R25 470 IN REG C30 0.1u C22 47u + E REG OUT 1 3 + VCC C23 0.1u C24 0.1u L2 10u 2 PORT1 GND 2 E D3V C31 0.47u C25 0.1u R26 18k for 74HC14 1 38 37 U3A 74HC14 INT1 R AVDD 39 40 VCOM 41 AVSS 42 RX0 43 NC 44 RX1 46 45 TEST1 D RX2 RX3 NC 48 47 D3V U2 IPS0 INT0 36 1 D 14 2 7 R27 1k LED1 K A D3V ERF D3V 2 NC OCKS0 35 3 DIF0 OCKS1 34 4 TEST2 CM1 33 5 DIF1 CM0 32 6 NC PDN 31 R38 47k R28 47k AK4114 C DIF2 8 C TEST1 C32 5p XTI 30 IPS1 XTO 29 9 P/SN DAUX 28 10 XTL0 MCKO2 27 11 XTL1 BICK 26 DIR_BICK 12 VIN SDTO 25 DIR_SDTO 1 7 4114_PDN C33 5p 2 X1 11.2896MHz SDTO A IN VCC 3 2 GND 1 TOTX141 LRCK 24 MCKO1 DIR_LRCK DIR_MCLK C36 10u C37 10u D3V PORT2 23 22 DVSS DVDD 21 C35 0.1u + 20 VOUT UOUT 19 COUT 18 BOUT 17 TX1 16 15 14 TVDD C34 0.1u + 13 TX0 B DVSS B R29 5.1 REG A C38 0.1u Title Size A3 Date: A B C D AKD4642EN-B Document Number Rev DIR/DIT Thursday, June 09, 2005 Sheet E 0 3 of 5 A B C D E U4 11 Y8 A8 9 12 Y7 A7 8 LRCK 13 Y6 A6 7 SDTI 14 Y5 A5 6 15 Y4 A4 5 CCLK 16 Y3 A3 4 CSN 17 Y2 A2 3 PDN 18 Y1 A1 2 10 GND G2 19 20 VCC G1 1 MCKI JP6 BICK2 E BICK E JP7 LRCK2 JP15 SDA JP8 LRCK DIR_LRCK 3-wire CDTI I2C D D C39 0.1u D3V 74LVC541 JP9 MCLK C REG PORT4 1 2 3 4 5 10 9 8 7 6 CTRL R30 10k R33 10k R35 10k R31 R32 R34 470 470 470 C DIR_MCLK JP10 BICK MCLK BICK LRCK SDTI VCC DIR_BICK PORT3 1 2 3 4 5 10 9 8 7 6 DSP CSN SCL/CCLK SDA/CDTI R36 D3V 10k JP14 CAD0 ADC SDTO B B JP11 SDTI DIR_SDTO DIR D3V K D3V R37 10k U3B 74HC14 A D3 HSU119 3 5 U3C 74HC14 14 6 7 4114_PDN 1 H 3 L 14 4 7 SW1 PDN C40 0.1u A 2 A Title Size A3 Date: A B C D AKD4642EN-B Document Number Rev LOGIC Thursday, June 09, 2005 0 Sheet E 4 of 5 A B C D E E E D D D3V U3F 74HC14 13 14 12 7 U3E 74HC14 11 14 10 7 U3D 74HC14 C 9 14 8 7 C B B A A Title Size A3 Date: A B C D AKD4642EN-B Document Number Rev PIN Monday, June 06, 2005 0 Sheet E 5 of 5
