AKD4683-B
AK4683 Evaluation Board Rev.0
FEATURE
AKD4683-B is an evaluation board for AK4683, a single chip 24bit CODEC that has two channels of ADC
and four channels of DAC with internal DIR, DIT. This board has interfaces with AKM’s evaluation boards
for A/D converter and D/A converter and makes easy to evaluate AK4683. Also this board has the digital
audio interface and then achieves the interface with digital audio systems via opt-connector or RCA
connector.
„ Ordering guide
AKD4683-B --- AK4683 Evaluation Board
10 wire flat cable for connection with printer port of PC (IBM-AT compatible machine),
control software for AK4683, driver for control software on Windows 2000/XP are
packed with this.
Control software does not work on Windows NT
Windows 2000/XP needs an installation of driver.
Windows 95/98/ME does not need an installation of driver.
FUNCTION
† On-board clock generator (use AK4114)
† Compatible with 2 types of digital audio interface
- Optical output/input and RCA input/output
- 10pin header for interface with external data source (x2)
† RCA connector for clock input with external clock source
† 10pin header for register control

EVALUATION BOARD MANUAL
„ Operating sequence
(1) Set up power supply lines.
[+12V]
(Orange) = +12V
[-12V]
(Blue) = -12V
[AVSS1] (Black) = 0V
[AVSS2] (Black) = 0V
[DVSS] (Black) = 0V
[PVSS]
(Black) = 0V
[HVSS] (Black) = 0V
[DGND] (Black) = 0V
Each supply line should be distributed from the power supply unit.
(2) Set up evaluation mode and jumper pins. (Refer to the following item.)
(3) Connect cables. (Refer to the following item.)
(4) Power on.
The AK4683 should be reset once bringing PDN (SW3) “L” upon power-up.
(5) Set up control software registers. (Refer to the following item.)
„ Evaluation modes
(1) DAC with internal DIR
1. Connection of connector
In case of digital input through RX0, optical connector PORT5 (TORX176) or RCA connector J14 (RX0) are
available. In case of digital input through RX1, RX2 or RX3, only the optical connector PORT5 is available.
2. Setting of jumper pin
RX0 and RX1-3 should not select optical connector at the same time.
In case of digital input through RX1, RX2 or RX3, set jumpers JP32 (RX1), JP34 (RX2) or JP36 (RX3) as Table
2. Set unused channels to GND.

Control Software Manual
„ Set-up of evaluation board and control software
1. Set up the AKD4683-B according to previous term.
2. Connect IBM-AT compatible PC with AKD4683-B by 10-line type flat cable (packed with AKD4683-B). Take care
of the direction of 10pin header. (Please install the driver in the CD-ROM when this control software is used on
Windows 2000/XP. Please refer “Installation Manual of Control Software Driver by AKM device control software”.
In case of Windows95/98/ME, this installation is not needed. This control software does not operate on Windows
NT.)
3. Insert the CD-ROM labeled “AKD4683-B Evaluation Kit” into the CD-ROM drive.
4. Access the CD-ROM drive, and double-click the icon of “akd4683-b_adc_dac.exe”and “akd4683-b_dir_dit.exe”,
and set up the control program.
akd4683-b_adc_dac.exe: AK4683 ADC/DAC control program
akd4683-b_dir_dit.exe: AK4683 DIR/DIT control program
5. Then evaluate according to the follows.
„ Operation flow
Keep the following flow.
1. Set up the control program according to explanation above.

„ Explanation of each dialog
1. [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”.
When writing the input data to register, click [OK] button. If not, click [Cancel] button.
2. [Function1 Dialog]: Dialog to write data by keyboard operation
Address Box: Input registers address in 2 figures of hexadecimal.
Data Box:
Input registers data in 2 figures of hexadecimal.
When writing the input data to register, click [OK] button. If not, click [Cancel] button.
3. [Function2 Dialog]: Dialog to evaluate ATT
This is a dialog corresponding to address: 0CH, 0DH, 0EH, 0FH, 10H, and 11H of AK4683.
Address Box:
Input registers address in 2 figures of hexadecimal.
Start Data Box:
Input starts data in 2 figures of hexadecimal.
End Data Box:
Input end data in 2 figures of hexadecimal.
Interval Box:
Data is written to register by this interval.
Step Box:
Data changes by this step.
Mode Select Box:
With checking 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
Without checking 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
When writing the input data to register, click [OK] button. If not, click [Cancel] button.
