AKD4702
Evaluation board Rev.A for AK4702
GENERAL DESCRIPTION
AKD4702 is an evaluation board for quickly evaluating the AK4702 , 2ch DAC with AV SCART switch.
Evaluation requires a audio/video analog analyzer, an analog video signal source, a digital audio signal
source, and a power supply. AKM’s ADC evaluation board can be also used for the audio source. Also
included is a AK4112B digital audio interface receiver which receives SPDIF compatible audio data. The
digital audio data is available via optical connector or BNC.

Note: 1. Each supply line should be distributed from the power supply unit.
2. JP9 (REG) should be open when the “+5V” jack is used.
3. JP8 (D-A) should be open when the “D5V” jack is used.
4. JP10 (VDD1) / JP11 (VDD2) should be open when the “VDD1” jack / “VDD2” jack are used
respectively.
2) Set-up the evaluation modes, jumper pins and DIP-switches. (Refer following sections.)
3) Connect the PORT3 (=µP-I/F) with PC by the enclosed 10-wire flat cable.
4) Set up the PC and execute the enclosed control software. (See “CONTROL SOFTWARE MANUAL”.)
5) Turn the power on.
6) Reset the AK4702 once by bringing the SW1 (PDN) “L”, and turn it to “H”.

n Evaluation mode
1) S/PDIF mode (Optical Link or BNC: default)
When the CM0 (DIP-switch S1_1 on board) is “L”, the AK4112B (DIR) generates MCLK, BICK, LRCK and
SDATA from the received bitstream through PORT2 (TORX176: optical link) or J2 (BNC). This mode is used
for the evaluation using CD test disk. The PORT1 (EXT) should be open.

CONTROL SOFTWARE MANUAL
n Introduction
This is a manual of software that controls the AK4702, 2ch DAC with AV SCART switch.
The enclosed software AKD4702.exe can control the registers of AK4702 using I2C control I/F.
n System Requirements
To use this software, the followings are required for PC.:
• Windows 95/98/ME/2000/XP. (This software does not operate on Windows NT.)
• Printer port
n Set-up of evaluation board and control software
1.
2.
3.
Set up the AKD4702.
Insert Connect IBM-AT compatible PC with AKD4702 by 10-line type flat cable (packed with AKD4702).
Take care of the direction of 10pin header. (Please install the driver in the CD-ROM disk 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.)
The CD-ROM disk labeled “AKD4702 Control Program ver 1.0” into the CD-ROM disk drive.
n Operations
[1] Execute the AKD4702.exe. Then the following window opens. The function of each button is shown below.
Clicking the button does each operation in the alone.
Write defalt to all resisters.
Read all resisters.
Close this window.
“ ”means “1”.
Write each byte.
Space means “0”.

[2] Write/Read Register
There are two ways to Write/Read register.
(1) Check box
After checking each box of each bit, click the “Write” or “Read” button in the right end. “ ” in each check box
means “1” and no check means “0”. Each check mark toggles by clicking. The address 08H is Read-only.

• These products and their specifications are subject to change without notice. Before considering any
use or application, consult the Asahi Kasei Microsystems Co., Ltd. (AKM) sales office or authorized
distributor concerning their current status.
• AKM assumes no liability for infringement of any patent, intellectual property, or other right in the

• AKM products are neither intended nor authorized for use as critical components in any safety, life

such use, except with the express written consent of the Representative Director of AKM. As used
here:
(a) A hazard related device or system is one designed or intended for life support or maintenance of

failure to function or perform may reasonably be expected to result in loss of life or in significant
injury or damage to person or property.
(b) A critical component is one whose failure to function or perform may reasonably be expected to
result, whether directly or indirectly, in the loss of the safety or effectiveness of the device or
system containing it, and which must therefore meet very high standards of performance and
reliability.
• It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or
otherwise places the product with a third party to notify that party in advance of the above content and
conditions, and the buyer or distributor agrees to assume any and all responsibility and liability for and
