S/N of ADC is 104.5dB (measurement). Therefore total S/N of op-amp circuit and ADC is 104.05dB (measurement: 103.9dB). <KM063700> -2- '00/9 ASAHI KASEI [AKD4527B Rev.D] 3) Frequency response of LPF 1st-order RC LPF is implemented on board to attenuate the noise around the internal sampling frequency of ADC (64fs=3.072MHz@fs=48kHz) Frequency response of 1st-order LPF | Amplitude |2 = 1/{1+(f/fc)2}; fc=1/2RC=169.3kHz@R=470,C=2000p (1nF capacitance prior to ADC is doubled because of full-differential input.) fin 20kHz 40kHz Frequency Response -0.060dB -0.236dB n Consideration for analog output circuit 3.0Vpp 6.0Vpp 22u AK4527 NJM5532 ROUT1 28 LOUT1 27 Same circuit ROUT2 26 Same circuit LOUT2 25 Same circuit ROUT3 24 Same circuit LOUT3 23 Same circuit 220 + - 10k 4.7k Signal 330p 4.7k 1) Frequency response of HPF The HPF is implemented on board to cancel the DC offset of analog output of AK4527B.

Therefore the output level of this board is 0.51dBV(=3.0Vpp) + 6.00dB = 6.51dBV = 6.0Vpp = 2.12Vrms. b) S/N (Theory: BW=20k+A) The output noise level of non-inverting amp -110.36dBV = -116.87dB (0dB=6.51dBV) S/N of DAC is 106.0dB (measurement) Therefore total S/N of op-amp circuit and DAC is 105.66dB (measurement: 105.5dB). <KM063700> -3- '00/9 ASAHI KASEI [AKD4527B Rev.D] c) Frequency response of filter Frequency response of the 1st-order filter | Amplitude |2 = K*{1+(f/fc2)2}/{1+(f/fc1)2}; K = 1+4.7k/4.7k = 2, fc1 = 1/2RC = 102.7kHz@R=4.7k,C=330p, fc2 = K*fc1 = 205.3kHz Frequency response referenced to output level of this board is as following table: fin DC 20kHz 40kHz 80kHz Frequency Response 0dB -0.121dB -0.452dB -1.448dB 145kHz -3dB -6dB If the frequency response of filter influences the system, 1st-order LPF is also available as the following figure: 3.0Vpp LPF 22u AK4527 ROUT1 28 LOUT1 27 Same circuit ROUT2 26 Same circuit LOUT2 25 Same circuit ROUT3 24 Same circuit LOUT3 23 Same circuit 6.0Vpp NJM5532 + - 10k 4.7k 220 Signal 3300p 4.7k Frequency response of this LPF | Amplitude |2 = 1/{1+(f/fc)2}; fc = 1/2RC = 219kHz@R=220,C=3300p Frequency response referenced to output level of this board is as following table: fin DC 20kHz 40kHz 80kHz Frequency Response 0dB -0.036dB -0.142dB -0.543dB 219kHz -3dB -dB The total frequency response of this board is sum of the external filter and internal LPF of AK4527B. These filters are effective to attenuate the high frequency noise since some measurement units is sensitive for out-of-band noise. <KM063700> -4- '00/9 ASAHI KASEI [AKD4527B Rev.D] n Operation sequence (1) Set up the power supply lines. [+12V] (orange jack) = +12 +15V [-12V] (blue jack) = -12 -15V [AGND] (black jack) = 0V [DGND] (black jack) = 0V Each supply line should be distributed from the power supply unit. 12V are supplied to analog interface. +12V is regulated to +5V and +3.3V by regulators(T1,T2). +5V is supplied to digital interface, AK4527B and TVDD of AK4112A. +3.3V is supplied to AVDD and DVDD of AK4112A. (2) Set up the evaluation mode and jumper pins. (See p.3.) (3) Connect Optical or BNC connector. [PORT2] (OPT_IN) : Optical input to RX1 of AK4112A [J10] (RX2) : BNC input to RX1 of AK4112A (4) Power on. The AK4527B, AK4112A and AK4353 should be reset once bringing PDN(SW1) "L" upon power-up. (5) Adjust the interface format Serial control is needed after the reset by SW1. The default value for interface format of AK4527B, AK4112A, and AK4353 is "Right justified, 20 bit", "Left justified, 24 bit", and "I2S", respectively. The software "4527.exe" packed with the AKD4527B is used for the set-up of the AK4527B. Evaluation mode 1 : DIF1-0 bit of the AK4527B should be set to "11" . Evaluation mode 2, 3: DIF1-0 bit of the AK4527B should be set to "10". Evaluation mode 4 : AK4112A and AK4527B should be set to adjust the format of DSP. (6) Set up software. The control mode of AK4527B and AK4112A is fixed to "serial". 10 The AKD4527B can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT3(uP-I/F) with PC by 10-line flat cable packed with the AKD4527B. Take care of the direction of connector. There is a mark at pin#1.
