ASAHI KASEI [AKD4642-B] AKD4642-B Evaluation board Rev.0 for AK4642 GENERAL DESCRIPTION AKD4642-B is an evaluation board for the AK4642, 16bit CODEC with built-in MIC/HP/SPK amplifier. The AKD4642 can evaluate A/D converter and D/A converter separately in addition to loop-back mode (A/D → D/A). The AKD4642 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD4642-B --- Evaluation board for AK4642 (Cable for connecting with printer port of IBM-AT compatible PC and control software are packed with this.

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 AK4642 and AK4114 via the regulator. 2) Set up the evaluation mode, jumper pins. (See the followings.) 3) Power on. The AK4642 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 (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. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX141). Nothing should be connected to PORT1 (DIR) and PORT3 (DSP).

(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. <KM075801> 2005/02 - 25 - A B C D E DGND JP1 GND AGND ROUT LOUT BEEP LIN2 RIN1 RIN2 E LIN1 E + C1 1u MPWR MUTET ROUT 25 26 27 LOUT BEEP 29 RIN2 30 LIN2 31 VCOM HPR 23 HPR 3 AVSS HVSS 22 4 AVDD HVDD 21 SPP C7 0.1u C8 0.1u JP12 HVDD PIEZO VCC Dynamic REG C VCOC SPP 20 6 I2C SPN 19 SPN 7 PDN MCKO 18 TEST2 8 CSN MCKI 17 MCKI 47k 51 PDN DVSS 16 15 10 BICK CDTI CCLK 9 DVDD 51 CSN 14 R7 C9 10u 5 LRCK R6 AK4642 10k 13 R3 R4 R5 10 2 SDTO 4.7n HPL 12 + C10 24 C5 0.1u REG C HPL SDTI C6 10u MPWR 11 + 1 + C4 2.2u LIN1 RIN1 U1 28 D 32 D 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 AKD4642-B Document Number Rev AK4642 Monday, September 13, 2004 Sheet E 0 1 of 5 A 4 C13 47u R15 20k R14 6.8 4 HPL E J1 HP 6 3 BEEP + 6 3 D + C14 1u C + E J2 BEEP B E HPR C15 47u C16 0.22u C17 0.22u R17 10 R18 10 R16 6.8 C18 1u LIN2 + J3 LIN2/RIN2 4 6 3 D D C19 1u + RIN2 R1 2.2k R19 10 MPWR J4 SPK-JACK SPP R2 2.2k SPK1 D1 J5 LIN1/RIN1 C JP3 RIN1 4 Piezo(EXT) Dynamic C3 1u + 6 3 JP3 SPKP RIN1 D2 C2 1u + JP2 LIN1 020S16 CN1 P 2 C Dynamic Piezo(EXT) 1 JP4 SPKN N LIN1 SPN R20 10 C20 1u R21 220 + B LOUT R22 20k C21 1u 4 B J6 LOUT/ROUT 6 3 + R23 220 ROUT R24 20k A A Title Size A3 Date: A B C D AKD4642-B Document Number Rev Input/Output Thursday, September 16, 2004 Sheet E 0 2 of 5 B C D E VCC REG T1 TA48M33F 1 IN L1 47u + REG OUT C23 0.1u C24 0.1u L2 10u 2 2 1 TORX141 + C29 10u C28 0.1u R25 470 C30 0.1u 1 40 39 R26 18k R VCOM 41 AVSS 42 RX0 43 NC 44 RX1 45 TEST1 46 RX2 47 NC RX3 U2 48 C31 0.47u D C25 0.1u REG 37 GND OUT E D3V C27 10u INT1 3 + VCC 38 PORT1 AVDD E C22 47u for 74HC14,74HC04 GND A D R27 1k U3A IPS0 INT0 1 36 2 LED1 ERF 2 D3V 1 74HC14 D3V 2 NC OCKS0 35 3 DIF0 OCKS1 34 4 TEST2 CM1 33 5 DIF1 CM0 32 6 NC PDN 31 XTI 30 R28 47k AK4114 C 4114_PDN C TEST 1 C32 5p DIF2 8 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 C33 5p 2 X1 11.2896MHz SDTO A IN VCC 3 2 GND 1 TOTX141 LRCK 24 MCKO1 23 22 DVSS DVDD 21 C35 0.1u DIR_LRCK + 20 VOUT UOUT 19 COUT 18 BOUT 17 TX1 16 15 DVSS 14 13 VCC PORT2 C34 0.1u + D3V TX0 B TVDD B DIR_MCLK C36 10u C37 10u R29 5.1 REG A C38 0.1u Title Size A3 Date: A B C D AKD4642-B Document Number Rev DIR/DIT Monday, September 13, 2004 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 CDTI 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 D JP8 LRCK DIR_LRCK D C39 0.1u D3V 74LVC541 VCC C PORT4 1 2 3 4 5 10 9 8 7 6 JP9 MCLK R30 10k R33 10k R35 10k R31 R32 R34 JP10 BICK 470 470 470 C DIR_MCLK MCLK BICK LRCK SDTI VCC DIR_BICK PORT3 1 2 3 4 5 10 9 8 7 6 DSP CSN CCLK CDTI D3V R36 10k CTRL ADC SDTO B B JP11 SDTI D3V 2 1 D3 HSU119 R37 10k U3B 3 U3C 4 74HC14 H 5 6 4114_PDN 74HC14 1 L 3 DIR_SDTO DIR SW1 PDN C40 0.1u A 2 A Title Size A3 Date: A B C D AKD4642-B Document Number Rev LOGIC Monday, September 13, 2004 0 Sheet E 4 of 5 A B C D E E E D D U3F 13 12 74HC14 U3E 11 10 74HC14 U3D C 9 C 8 74HC14 B B A A Title Size A3 Date: A B C D AKD4642-B Document Number Rev PIN Thursday, September 16, 2004 0 Sheet E 5 of 5
