| ASAHI KASEI [AKD5358A-B] AKD5358A-B AK5358A Evaluation Board Rev.0 GENERAL DESCRIPTION AKD5358A-B is an evaluation board for the digital audio 24bit 96kHz A/D converter, AK5358A. AKD5358A-B has analog input circuits and a digital interface transmitter,and can achieve the interface with digital audio systems via opt-connector.

Evaluation Board Manual Operation sequence 1) Set up the power supply lines. [VA] (red) = +15V [VD] (orange) = 2.7 5.5V [VCC] (red) = 3.3V [AGND] (black) = 0V [DGND] (black) = 0V : for VA of AK5358A (typ. 5.0V) : for VD of AK5358A, 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 AK5358A 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 AK5358A through PORT1. JP5 (MCLK) should be open. The DIF1 of SW1 (MODE) should be set to "H". JP5 MCLK 2006/08 ASAHI KASEI [AKD5358A-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 AK5358A 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) VA REG : Select VA for AK5358A : 5V Supply from VA connector 4. JP4 (VD) : Select VD for AK5358A Select VD 2006/08 ASAHI KASEI [AKD5358A-B] DIP Switch set up [SW1] (MODE1): Setting the evaluation mode for AK5358A and AK4114 ON is "H", OFF is "L".

Mode Setting of AK5358A 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 AK5358A and AK4114. Keep "H" during normal operation. 2006/08 ASAHI KASEI [AKD5358A-B] Analog Input Circuits Analog signal is input via J1(RIN) and J2(LIN) of RCA connectors.
