| ASAHI KASEI [AKD4528] AKD4528 AK4528 Evaluation Board Rev.C GENERAL DESCRIPTION The AKD4528 is an evaluation board for the AK4528, the 24Bit A/D & D/A converter. The AKD4528 can evaluate A/D converter and D/A converter separately in addition to Loopback mode (A/DD/A). The AKD4528 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD4528 --- AK4528 Evaluation Board (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 Digital interface - DIT (AK4353), DIR (AK4112B) with optical output/input. 10pin header for serial control interface -15V +15V Regulator AGND DGND LIN RIN Input Buffer AK4112B (DIT) AK4353 (DIT) Opt In Opt Out AK4528 LOUT ROUT Output Buffer 10pin Header Control Data Figure 1. AKD4528 Block Diagram * Circuit diagram and PCB layout are attached at the end of this manual. 2005/11 ASAHI KASEI [AKD4528] 1. Analog Input Buffer Circuit The ADC inputs are full differential and the input resistance is 27k (typ. @fs=44.1kHz). The input signal range scales with the VREF voltage and nominally 0.56 x VREF Vpp. It is recommended that the input DC bias voltage is 2.9V(The bias is a voltage divided by resistors (3.3k and 4.7k) from VA in figure 2. The ADC output data format is 2's complement. The DC offset including ADC own DC offset removed by the internal HPF (fc=0.9Hz@fs=44.1kHz). The AK4528 samples the analog inputs at 64fs. The digital filter rejects noise above the stopband except for multiples of 64fs. A simple RC filter may be used to attenuate any noise around 64fs though most audio signals do not have significant energy at 64fs. Figure 2 is an example of differential input circuit. 5.96Vpp 4.7k 2.8Vpp 4.7k 330 330 AINR3 2.8Vpp 4.7k + NJM5532 Vop+ 10k + VA Vop3.3k AINL+ 4 AINL5 Vop+/-=+/-15V VA=5V Same circuit BIAS 4.7k + 10u 0.1u 22u Signal AK4528 AINR+ 2 1.5nF Input RC filter response : fc = 160kHz, g = -0.07dB at 20kHz, -0.26dB at 40kHz. Figure 2. Differential Input Buffer Example 2.Analog Output Buffer Circuit The 2nd-order LPF (fc=93.2kHz, Q=0.712) which adds differential output of AK4528 is implemented on the board. When the further attenuation of the out-band noise is needed, some additional LPF is required. NJM5532D is used for op-amp. Analog signal is output through BNC connectors (AOUTL, AOUTR) on board, and the output level of AK4528 is about 5.4Vp-p. 4.7k AOUT200 470p 4.7k 3300p 4.7k AOUT+ 4.7k 470p 200 +Vop + -Vop Analog Out fc=93.2kHz, Q=0.712, g=-0.1dB at 40kHz Figure 3.

Set up Parallel/Serial mode control When P/S= "H", the AK4528 becomes to the parallel mode. DIF pin selects the audio interface format, and DFS, CKS1, and CKS0 pins select the master clock frequency. When P/S= "L", the AK4528 becomes to the serial mode. The CKS1, CKS0 and DIF pins are changed to CDTI, CCLK and CSN pins respectively. The DEM1, DEM0 and DFS are ORed between pins and register respectively, so those are able to control by pins even in serial mode. When all the functions are controlled by register, DEM1, DEM0 and DFS pins should be set to "L". 2.

(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. 2005/11 5 4 3 2 1 TX PORT3 5 IN VCC IF 6 6 GND TOTX176 5 4 3 2 1 R59 +5V 1k C66 0.1u D R60 5.1 C67 10u 4353_MCLK R2 100 4353_BICK R3 100 4528_SDTO R4 100 PDN 4353_LRCK 4353_CSN 4353_CCLK 4353_CDTI + C68 0.1u U4 R12 5.1 +3.3V +5V C69 0.1u C71 0.1u C70 + 10u +5V + + C50 10u C4 10u C5 0.1u + C2 10u + C3 0.1u U2 D 1 DVDD CM0/CDTO 28 CM0 R1 100 1 2 3 4 5 6 7 8 9 10 11 12 MCKO DZF TX NC DVDD AVDD DVSS AVSS MCKI VCOM BICK AOUTL SDTI AOUTR LRCK CAD0 PDN CAD1 CSN I2C SCL/CCLK TTL SDA/CDTI TST 24 23 22 21 20 19 18 17 16 15 14 13 2 DVSS CM1/CDTI 27 CM1 3 TVDD OCKS1/CCLK 26 OCKS1 V/TX C6 5p 4 V/TX OCKS0/CSN 25 OCKS0 AK4353 (DIT) C7 5p C 2 5 X1 11.2896MHz XTI MCKO1 24 4112_MCLK +5V 1 6 XTO MCKO2 23 R17 4528_SDTO 100 U3A R5 LE1 for 74HCT14, 74HCT157 +5V C25 47u + R6 18k PDN 7 PDN DAUX 22 C 8 R BICK 21 4112_BICK 1 2 1k R7 ERF LE2 74HCT14 9 +3.3V C8 10u + C9 0.1u 1 +5V L1 10u AVDD SDTO 20 4112_SDTO C26 0.1u C27 0.1u 10 AVSS LRCK 19 3 4112_LRCK U3B 4 1k R8 FS96 LE3 2 6 RX 5 PORT1 6 GND VCC GND 5 OUT 74HCT14 4 3 2 1 11 C10 0.1u C11 + 10u RX1 ERF 18 5 U3C TORX176 TORX176 1 R9 470 3 +3.3V JP1 2 RX COAX 4112_DIF0 12 RX2/DIF0 FS96 17 6 1k R10 AUTO LE4 B 74HCT14 4112_DIF1 13 RX3/DIF1 P/SN 16 +5V V/TX V B J2 COAX D2 1S1588 R11 75 C12 0.1u 4112_DIF2 14 RX RX4/DIF2 AUTO 15 9 U3D 8 1k V 74HCT14 AK4112B (DIR) +5V T2 LP2950A +3.3V 1 2 3 4 5 6 7 SW2 14 13 12 11 10 9 8 1 C13 0.1u C14 47u + GND OUT IN 3 C1 47u + C15 0.1u +5V 4112_DIP RP2 A 7 6 5 4 3 2 1 OCKS0 OCKS1 CM0 CM1 DIF0 DIF1 DIF2 2 OCKS0 OCKS1 CM0 CM1 4112_DIF0 4112_DIF1 4112_DIF2 Title A 47k Size Document Number AKD4528 3 1 Rev A3 Date: 5 4 3 2 AK4112B AK4353 DIR DIT Sheet of Monday, October 03, 2005 1 C 5 4 3 2 1 +15V T1 NJM78M05FA Bias L6 10u 1 2 L2 +5V Digital Ground JP2 GND Analog Ground 1 C16 0.1u D GND IN OUT 3 C17 0.1u C18 + 47u 5.1 AK4528_+5V 2 D C19 2.2u L3 1 C20 0.1u U1 (short) 2 1 C 6 VREF VD 23 +5V 1S1588 + D1 R13 10k C23 10u C24 0.1u 7 AGND VT 22 8 11 H L U3E 10 13 U3F VA DEM1 21 DEM1 12 PDN 4353_MCLK 4353_LRCK 4353_BICK P/S R14 100 R15 100 R16 100 C29 0.1u 74HCT14 74HCT14 9 P/S DEM0 20 DEM0 SW3 PDN 10 MCLK PDN 19 PDN 4112_MCLK 4112_LRCK 4112_BICK 4112_SDTO 11 LRCK DFS 18 DFS 12 BICK CSN / DIF 17 CSN/DIF B 4528_SDTO R18 13 SDTO CCLK / CKS1 16 CCLK/CKS1 14 100 SDTI CDTI/CKS0 15 CDTI/CKS0 RP1 AK4528 +5V R19 2.2k R20 2.2k R21 2.2k U5 1A 1B 2A 2B 3A 3B 4A 4B 1 2 3 4 5 A PORT2 10 CSN 9 CCLK 8 CDTI 7 6 CR-I/F DIF CKS1 R24 470 R23 470 R22 470 CKS0 2 3 5 6 11 10 14 13 1 15 1Y 2Y 3Y 4Y 4 7 9 12 CSN/DIF CCLK/CKS1 CDTI/CKS0 A 4353_CSN 4353_CCLK 4353_CDTI P/S A/B G 74HCT157 Title Size Document Number 5 4 3 + + + VCOM AOUTR+ 28 AOUTR+ AINR+ 2 AINR+ AOUTR- 27 AOUTR- AINR- 3 AINR- AOUTL+ 26 AOUTL+ AINL+ 4 AINL+ AOUTL- 25 AOUTL- AINL- 5 AINL- DGND 24 C21 0.1u C22 10u AK4528_+5V C 1 2 3 4 5 6 7 SW1 +5V 14 13 12 11 10 9 8 B AK4528_DIP 7 6 5 4 3 2 1 P/S DEM1 DEM0 DFS DIF CKS1 CKS0 P/S DEM1 DEM0 DFS DIF CKS1 CKS0 47K AKD4528 AK4528 Sheet 1 Rev A3 Date: 2 C 2 of Monday, October 03, 2005 3 5 4 3 2 1 R25 4.7k R26 4.7k R27 4.7k D VOP- D U6A NJM5532 VOP+ 8 8 4 Bias R40 3.3k R39 330 AINLC38 0.1u C 8 R37 4.7k AOUTL+ R38 200 VOP+ R41 4.7k C40 470p C39 10u + R35 4.7k R42 4.7k R43 4.7k R44 4.7k VOPVOP- 8 B 4 NJM5532 VOP+ 8 Bias R57 3.3k R56 330 AINRC42 0.1u C49 10u + R50 4.7k AOUTR+ R54 4.7k R55 200 VOP+ R58 4.7k C51 470p -15V A +15V 8 1 + + C52 47u L4 2 + + for NJM5532 VOPC59 47u C58 0.1u + + + + + 1 L5 2 + C60 10u for NJM5532 VOP+ + C61 0.1u C62 10u C63 0.1u + Title (short) (short) C53 10u C54 0.1u C55 10u C56 0.1u C57 10u C64 10u C65 0.1u 5 4 3 2 + C45 3300p 5 7 U8B NJM5532 + - + + R47 560 22u 5 U7B 3 - - 6 4 J5 RIN C41 + + R45 10k 4 7 R46 4.7k 2 U7A 1 NJM5532 VOP+ R48 330 AINR+ AOUTR- R49 4.7k R52 200 VOP- C44 1.5n + C34 3300p 3 1 U8A NJM5532 + - + + + R30 560 22u 3 5 - - 2 4 J3 LIN C30 + + R28 10k VOP- 4 1 R29 4.7k 6 7 U6B NJM5532 VOP+ R31 330 AINL+ AOUTL- R32 4.7k R33 200 VOP- C32 470p C33 1.5n 2 R34 220 J4 AOUTL C35 22u R36 10k C C43 470p B 6 R51 220 J1 AOUTR C46 22u R53 10k A Size Document Number AKD4528 Analog_I/O Sheet 1 Rev A3 Date: C 3 of Monday, October 03, 2005 3 |
