Evaluation board Rev.A for AK4584
GENERAL DESCRIPTION AKD4584 is an evaluation board for the 24bit 96kHz CODEC, AK4584. The AKD4584 can evaluate A/D converter D/A converter separately in addition to loopback mode (A/D D/A). The AKD4584 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide

Operation sequence
1) Set up the power supply lines. [AVDD] (red) = 4.75 5.25V [TVDD] (orange) = 2.7 5.25V [VCC] (red) = 5.0V [VDD] (red) = 5.0V [AGND] (black) = 0V [DGND] (black) = 0V : for AVDD, DVDD, PVDD of AK4584 (typ. 5.0V) : for TVDD of AK4584 (typ. 3.0V) : for logic (typ. 5.0V) : for logic (typ. 5.0V) : 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 AK4584 should be reset once bringing SW1 "L" upon power-up.
Evaluation mode
(1) Slave mode In case of AK4584 evaluation using AK4114, it is necessary to correspond to AK4584's and AK4114's audio interface format. About AK4584's audio interface format, refer to AK4584's datasheet. About AK4114's audio interface format, see Table2. (1-1) A/D evaluation using DIT function of AK4584 (1-2) A/D evaluation using DIT function of AK4114 (1-3) D/A evaluation using DIR function of AK4114 (1-4) All interfacing signal (MCLK, BICK, LRCK) are fed from the external circuit (1-1) A/D evaluation using DIT function of AK4584 Using J5 (EXT), PORT4 (DIT) and J6 (TX). Nothing should be connected to J7 (RX), PORT1 (DIR), PORT5 (DIR) and PORT6 (ROM). Remove the X'tal (X1). The bi-phase data is output from TX3. JP6 (EXT) should be open.

2. Control Software Manual Set-up of evaluation board and control software
1. Set up the AKD4584 according to previous term. 2. Connect IBM-AT compatible PC with AKD4584 by 10-line type flat cable (packed with AKD4584). Take care of the direction of 10pin header. (This control software does not operate on Windows NT/2000, therefore please operate it on Windows 95/98.) 3. Insert the floppy-disk labeled "AKD4584 Control Program ver 1.0" into the floppy-disk drive. 4. Access the floppy-disk drive and double-click the icon of "AKD4584-1.exe" and "AKD4584-2" to set up the control program. 5. Then please evaluate according to the follows.
Explanation of each buttons

Read the all register of AK4584. Dialog to write data by keyboard operation. Dialog to evaluate IPGA and OATT. Dialog to write data by mouse operation. Read each register data by mouse operation.
Explanation of each dialog
1. [Function1 Dialog] : Address Box: Data Box: Dialog to write data by keyboard operation
Input register address in 2 figures of hexadecimal. Input register data in 2 figures of hexadecimal.
If you want to write the input data to AK4584, click "OK" button. If not, click "Cancel" button. 2. [Function2 Dialog] : Dialog to evaluate IPGA and OATT
This dialog corresponds to only addr=04H, 05H, 06H, 07H. Address Box: Input register address in 2 figures of hexadecimal. Start Data Box: Input start data in 2 figures of hexadecimal. End Data Box: Input end data in 2 figures of hexadecimal. Interval Box: Data is written to AK4584 by this interval. Step Box: Data changes by this step. Mode Select Box: If you check this check box, data reaches end data, and returns to start data. [Example] Start Data = 00, End Data = 09 Data flow: 00 01 02 03 04 05 06 07 08 09 09 08 07 06 05 04 03 02 01 00 If you do not check this check box, data reaches end data, but does not return to start data. [Example] Start Data = 00, End Data = 09 Data flow: 00 01 02 03 04 05 06 07 08 09 If you want to write the input data to AK4584, click "OK" button. If not, click "Cancel" button.

3. [Write Dialog] : Dialog to write data by mouse operation There are dialogs corresponding to each register. Click the "Write" button corresponding to each register to set up the dialog. If you check the check box, data becomes "H" or "1". If not, "L" or "0". If you want to write the input data to AK4584, click "OK" button. If not, click "Cancel" button.
Operation flow
Keep the following flow surely. 1. Set up the control program according to explanation above. 2. Click "Port Setup" button. 3. Click "Write default" button. 4. Then set up the dialog and input data.
Indication of data
Input data is indicated on the register map. Red letter indicates "H" or "1" and blue one indicates "L" or "0". Blank is the part that is not defined in the datasheet.
Attention on the operation
If you set up Function1 or Function2 dialog, input data to all boxes. Attention dialog is indicated if you input data or address that is not specified in the datasheet or you click "OK" button before you input data. In that case set up the dialog and input data once more again. These operations does not need if you click "Cancel" button or check the check box.
