n Operation sequence
1) Set up the power supply lines. [VA] (orange) = 2.2 3.3V [D2V] (orange) = 1.8 3.3V [VCC] (red) = 3.6 5.0V [AGND] (black) = 0V [DGND] (black) = 0V : for VA of AK5354 (typ. 2.5V) : for D2V of 74LVC541 (typ. 2.5V) : for logic : for analog ground (including VSS of AK5354) : for logic ground
Each supply line should be distributed from the power supply unit. D2V and VA must be same voltage level. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) Note : Evaluation mode of the AK5354 is fixed to I2S compatible on the board. 3) Power on. The AK5354 and AK4353 should be reset once bringing SW1 = SW2 = "L" upon power-up.
n Evaluation mode
Applicable Evaluation Mode (1) Evaluation of A/D using DIT (Optical Link) (2) Evaluation of A/D using D/A converted data (3) All interface signals including master clock are fed externally.
(1) Evaluation of A/D using DIT (Optical Link) PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX176). It is possible to connect AKM's D/A converter evaluation boards on the digitalamplifier which equips DIR input. Nothing should be connected to PORT3 (ROM). In case of using external clock through a BNC connector (J3), select EXT on JP6 (CLK) and short JP5 (XTE) and open JP7 (EXT).

(2) Evaluation of A/D using D/A converted data It is possible to make evaluation in the form of analog inputs and analog outputs by interfacing with various AKM's D/A evaluation boards with PORT3 (ROM).

n The function of the toggle SW
Upper-side is "H" and lower-side is "L". [SW1] (PDN): Resets the AK5354. Keep "H" during normal operation. [SW2] (DIT): Resets the AK4353. Keep "H" during normal operation.
n Serial Control
The AK5354 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT2(CTRL) with PC by 10-line flat cable packed with the AKD5354. Take care of the direction of connector. There is a mark pin#1 to connector.

2. Control Software Manual n Set-up of evaluation board and control software
1. Set up the AKD5354 according to previous term. 2. Connect IBM-AT compatible PC with AKD5354 by 10-line type flat cable (packed with AKD5354). Take care of the direction of 10pin header. (This control software does not operate on Windows NT, therefore please operate it on Windows95/98.) 3. Insert the floppy-disk labeled "AKD5354 Control Program ver 1.0" into the floppy-disk drive. 4. Access the floppy-disk drive and double-click the icon of "AKD5354.exe" to set up the control program. 5. Then please evaluate according to the follows.

n 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 AK5354, click "OK" button. If not, click "Cancel" button. 2. [Function2 Dialog] : Dialog to evaluate IPGA
This dialog corresponds to only addr=03H. 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 AK5354 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 AK5354, 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 AK5354, click "OK" button. If not, click "Cancel" button.
n 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.

n 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.
n 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.
