ASAHI KASEI [AKD5358-B] AKD5358-B AK5358 Evaluation Board Rev.0 GENERAL DESCRIPTION AKD5358-B is an evaluation board for the digital audio 24bit 96kHz A/D converter, AK5358. AKD5358-B has analog input circuits and a digital interface transmitter,and can achieve the interface with digital audio systems via opt-connector. Ordering guide AKD5358-B --AK5358 Evaluation Board FUNCTION * DIT (AK4114) with optical output VA,VD AGND,DGND LIN RIN AK5358 AK4114 (DIT) Opt Out DSP Data 10pin Header Figure 1. AKD5358-B Block Diagram * Circuit diagram and PCB layout are attached at the end of this manual. 2005/09 ASAHI KASEI [AKD5358-B] 1. Evaluation Board Manual Operation sequence 1) Set up the power supply lines. [VA] (red) = 2.7 5.5V or +15V [VD] (orange) = 2.7 5.5V [VCC] (red) = 3.3V [AGND] (black) = 0V [DGND] (black) = 0V : for VA of AK5358 (typ. 5.0V) : for VD of AK5358, 74HC14 (typ. 5.0V) : for AK4114 : for analog ground : for logic ground Each supply line should be distributed from the power supply unit. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) 3) Power on. The AK5358 and AK4114 should be reset once bringing SW2 = "L" upon power-up. Evaluation mode (1) Slave Mode (1-1) A/D evaluation using DIT function of AK4114 PORT2 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX141). It is possible to connect AKM's D/A converter evaluation boards on the digital-amplifier, which equips DIR input. Nothing should be connected to PORT1 (DSP). JP5 MCLK (1-2) All interface signals including master clock are fed externally. PORT1 (DSP) is used. All interface signals (MCLK, SCLK, LRCK) are provided to the AK5358 through PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to "H". JP5 MCLK 2005/09 ASAHI KASEI [AKD5358-B] (2) Master Mode (2-1) A/D evaluation using DIT function of AK4114 PORT2 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX141). It is possible to connect AKM's D/A converter evaluation boards on the digital-amplifier, which equips DIR input. Nothing should be connected to PORT1 (DSP). The DIF1 of SW1 (MODE) should be set to "H". JP5 MCLK (2-2) Master clock is fed externally. PORT1 (DSP) is used. MCLK is provided to the AK5358 through PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to "H". JP5 MCLK Other jumper pins set up 1. JP1 (GND) : Analog ground and Digital ground OPEN : Separated. SHORT : Common. (The connector "DGND" can be open.) 3. JP3 (VA) : Select VA for AK5358 VA : Supply from VA connector 2005/09 ASAHI KASEI [AKD5358-B] DIP Switch set up [SW1] (MODE1): Setting the evaluation mode for AK5358 and AK4114 ON is "H", OFF is "L". CKS1 should be set by JP2. No. 1 2 3 4 Name CKS0 CKS2 DIF DIF1 OFF ("L") See Table 2 MSB justified AK4114 Master mode Table 1.

Mode Setting of AK5358 Note: AK4114 does not support MCLK=384fs/512fs/768fs. PORT1 (DSP) should be used when MCLK=384fs/512fs/768fs. The function of the toggle SW Upper-side is "H" and lower-side is "L". [SW2] (PDN): Resets the AK5358 and AK4114. Keep "H" during normal operation. 2005/09 ASAHI KASEI [AKD5358-B] Analog Input Circuits Analog signal is input via J1(RIN) and J2(LIN) of RCA connectors.
