ASAHI KASEI [AKD4537] AKD4537 Evaluation board Rev.B for AK4537 GENERAL DESCRIPTION AKD4537 is an evaluation board for the AK4537, 16bit CODEC with built-in MIC/HP/SPK amplifier. The AKD4537 can evaluate A/D converter and D/A converter separately in addition to loop-back mode (A/D → D/A). The AKD4537 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. n Ordering guide AKD4537 --- Evaluation board for AK4537 (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.)

[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 AK4537 and AK4114 via the regulator. 2) Set up the evaluation mode, jumper pins. (See the followings.) 3) Power on. The AK4537 and AK4114 should be reset once bringing SW2 “L” upon power-up. n 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, MOUT+) using DIR of AK4114 (1-3) Evaluation of Loop-back using AK4114 (1-4) All interface signals including master clock are fed externally. AK4114’s audio interface format is fixed to I2S compatible. AK4114 does not operate under fs = 32kHz, this mode corresponds to fs = 32kHz or more.

(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. <KM069501> 2002/11 - 23 - A B C D E MOUT+ JP1 GND AGND ROUT E LOUT RIN2 LIN2 BEEPM BEEPL E BEEPR DGND 1 MICR JP11 EXT/MICR 2 40 MIN MOUT2 ROUT 41 42 43 MOUT- LOUT 44 45 MOUT+ 46 RIN2 47 LIN2 48 BEEPM 50 49 BEEPR D BEEPL 51 + RIN1 U1 LIN1 C5 1u + + C44 1u 52 C4 1u C6 1u D MICOUTL MUTET 39 MICOUTR HPL 38 HPL EXT/MICR HPR 37 HPR MPE HVSS 36 MPI HVDD 35 REG SPN 34 SPN SPP 33 AVSS M/S 32 AVDD XTI/MCKI 31 PVDD XTO 30 PVSS DVSS 29 VCOC DVDD 28 EXT C8 1u 3 + 2.2k 4 C10 0.1u R10 2.2k 5 + R9 C11 10u C12 1u 6 INT + 7 C13 2.2u + AK4537 VCOM C SPP C14 0.1u 8 C15 C16 10u 0.1u + 9 REG 10 C17 0.1u 11 MCKI C18 0.1u R13 10 B INT/MICL 12 + C C19 10u B NC MASTER SLAVE JP4 M/S 26 MCKO 27 R18 51 BICK LRCK R17 51 25 BICK 24 23 R16 51 SDTO SDTI CDTO CDTI CCLK CSN PDN R15 51 A LRCK SDTO 22 SDTI 21 I2C 20 CDTO NC 19 CDTI/SDA 18 CCLK/SCL 17 PDN 15 14 16 NC CAD0 13 C20 4.7n CSN/CAD1 R14 10k A TEST1 Title Size A3 Date: A B C D AKD4537 Document Number Rev AK4537 Monday, August 12, 2002 Sheet E B 1 of 5 A B C D E REG E 1 BPM R1 20k BEEPM MUTE JP2 BPMS C3 1u R4 20k C R5 BPR B BEEPR 10k Q2 2SC3327 + BEEPL J4 MOUT+ R2 220 C2 E + J2 BEEP B C + E Q1 RN2202 3 2 C1 1u E MOUT+ 22u C7 47u + J3 LIN2/RIN2 J6 HP + HPL C45 1u R3 47k R7 16 + LIN2 HPR C9 47u R8 16 REG D D 1 E + RIN2 E Q4 B Q3 RN2202 3 B MUTE C 2 C46 1u 2SC3327 R12 10k C MICR J1 MIC EXT EXT C C JP3 MIC INT SPK1 INT 020S16 CN1 SPN 2 SPP 1 L R B B C47 22u + R37 220 J5 LOUT/ROUT LOUT R36 10k C48 22u R39 220 + A A ROUT R38 10k Title Size A3 Date: A B C D AKD4537 Document Number Rev Input/Output Monday, August 12, 2002 Sheet E B 2 of 6 B C D E VCC 1 L2 47u 6 5 6 5 GND VCC GND OUT DIR 4 3 2 1 2 PORT1 E C21 0.1u + C28 10u C27 0.1u C22 0.1u VCC L1 10u for 74HC14, 74HCT157, 74HCT04 1 2 C23 0.1u C24 47u T1 TA48M33F IN + GND A REG OUT C25 0.1u C26 0.1u E C29 10u R19 470 + REG C30 0.1u 1 37 INT1 38 AVDD 39 40 R AVSS R20 18k VCOM 41 42 RX0 43 NC 44 RX1 45 TEST1 47 46 RX2 D NC RX3 U2 48 C31 0.47u D R21 1k U3A IPS0 INT0 36 1 LED1 ERF 2 2 VCC 1 74HCT04 3 4 5 NC OCKS0 DIF0 OCKS1 TEST2 CM1 DIF1 CM0 AK4114 C 6 7 NC DIF2 35 34 33 32 C PDN 31 4114_PDN C32 5p XTI 30 1 2 X1 11.2896MHz IPS1 XTO P/SN DAUX C33 5p 29 2 8 U3C 9 28 6 U3B 5 74HCT04 10 XTL0 MCKO2 27 XTL1 BICK 26 DIR_BICK SDTO 25 DIR_SDTO 4 3 SDTO 74HCT04 DAUX 11 B B LRCK 24 MCKO1 23 22 DVSS DVDD 21 C35 0.1u DIR_LRCK + 20 VOUT UOUT 19 COUT 18 BOUT 17 TX0 TX1 16 14 13 VCC C34 0.1u + VCC 15 DVSS VIN TVDD 12 DIR_MCLK C36 10u C37 10u REG PORT2 5 A 6 5 6 IN VCC IF GND DIT 4 3 2 1 A R22 1k C38 0.1u Title Size A3 Date: A B C D AKD4537 Document Number Rev DIR/DIT Monday, August 12, 2002 Sheet E B 3 of 5 A B C D E U4 11 MCKI 9 Y8 A8 12 Y7 A7 8 LRCK 13 Y6 A6 7 SDTI 14 Y5 A5 6 Y4 A4 Y3 A3 Y2 A2 JP5 BICK2 E E BICK JP6 LRCK2 JP7 LRCK DIR_LRCK R23 51 15 CDTI 5 R24 51 16 CCLK 4 R25 51 D CSN 17 PDN 18 10 Y1 A1 GND G2 VCC G1 3 D 2 19 C39 0.1u 20 REG 1 74LVC541 VCC C PORT4 1 2 3 4 5 10 9 8 7 6 JP8 MCLK R26 10k R29 10k R31 10k R27 R28 R30 2 3 4 5 6 7 8 9 CSN CCLK CDTI CDTO A1 A2 A3 A4 A5 A6 A7 A8 1 19 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 18 17 16 15 14 13 12 11 MCLK BICK LRCK SDTI VCC DIR_BICK 10 9 8 7 6 VCC R32 10k 74HCT541 ADC CDTO B PORT3 1 2 3 4 5 ROM G1 G2 R33 51 CTRL JP9 BICK U5 470 470 470 C DIR_MCLK DAUX B JP10 SDTI VCC 2 R34 10k U6A 1 2 74HC14 4 74HC14 5 6 SW1 MUTE R35 10k U6E 11 MUTE 74HC14 L U6D 10 74HC14 H 9 8 4114_PDN 74HC14 SW2 PDN C41 0.1u A 2 C40 0.1u 2 A D2 HSU119 3 3 U6C 1 H 3 L U6B 1 D1 HSU119 DIR_SDTO DIR 1 1 2 VCC Title Size A3 Date: A B C D AKD4537 Document Number Rev LOGIC Monday, August 12, 2002 B Sheet E 4 of 5 A B C D E E E D D U6F 13 12 74HC14 U3D 9 8 74HCT04 U3E 11 10 74HCT04 C C U3F 13 12 74HCT04 B B A A Title Size A3 Date: A B C D AKD4537 Document Number Rev PIN Monday, August 12, 2002 B Sheet E 5 of 5
