AKD4353
Evaluation board Rev.A for AK4353
GENERAL DESCRIPTION
The AKD4353 is an evaluation board for AK4353, 96kHz 24bit D/A converter with DIT. The AKD4353 has
a digital interface with AKM’s wave generator using ROM data and AKM’s A/D converter evaluation
boards. Therefore, it is easy to evaluate the AK4353.

Evaluation board for AK4353
(Cable for connecting with printer port of IBM-AT compatible PC
and control software are packed with this.)
FUNCTION
• On-board clock generator
• Compatible with 2 types of interface
- Direct interface with AKM’s A/D converter evaluation boards
and direct interface with AKM’s signal generator(AKD43XX) by 10pin header
- On-board CS8414 as DIR which accepts optical input
• BNC connector for external clock input
• 10pin header for serial control interface
• On-board mute circuit for analog output
• Optical output for TX output

n External analog circuit
J1(AOUTL) and J2(AOUTR) are used. The analog output signal range is nominally 3.1Vpp@5V. It is proportional
to AVDD (Vout=0.62xAVDD).
n Operation sequence
1) Set up the power supply lines.
[AVDD] (red) = 2.7∼5.5V : for AVDD of AK4353
[3V] (orange)
= 2.7∼5.5V : for DVDD of AK4353
[5V] (red)
= 3.4∼5.5V : for logic
[AGND] (black)= 0V
: for analog ground (including AVSS and DVSS of AK4353)
[DGND] (black)= 0V
: 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 AK4353 should be reset once bringing SW1(-PD) “L” upon power-up.

4) Connect PORT2 with PC.
Connect PORT2 with printer port (parallel port) of IBM-AT compatible PC by 10-line flat cable packed with
the AKD4353. Take care of the direction of connector. There is a mark at 1pin. The direction of PORT2 is as
the following figure.

5) Set up the software.
Use the software named “AKD4353 Control Program” packed with the AKD4353.
n Evaluation mode
1) Using A/D converted data <default>
PORT3 (ADC/ROM) is used to interface with various AKM’s A/D converter evaluation boards. In case of
using external clock through a BNC connector (J4), select BNC on JP14 (CLK) and short JP15 (XTE).

2) Ideal sine wave generated by ROM data
Digital signals generated by AKD43XX are used. PORT3 (ADC/ROM) is used to interface with AK43XX.
Master clock is sent from AKD4353 to AKD43XX and LRCK, BICK, SDTI are supplied from AKD43XX to
AKD4353. In case of using external clock through a BNC connector (J4), select “BNC” on JP14 (CLK) and
short JP15 (XTE).

LRCK, SDTI from the received data through optical connector. In this case, the EXT bit of AK4353 should be
“1” (External clock mode). Select “RCA” or “OPT” on JP16 (RCA/OPT) in case of using RCA connector (J3)
or optical connector (PORT4: TORX174).

n Serial control mode
The AK4353 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 AKD4353.
There are two modes: 3-wire serial & I2C bus. JP4 should be shorted at 3-wire serial control mode.
Chip address can be selected by SW2(MODE)-No.1(CAD1) and No.2(CAD0).

Open: Separated <default>
Short: Common (The connector “DGND” can be open.)
[JP2](5V-3V): DVDD of AK4353 and power supply to logic

AKD4353 Control Program ver 2.0 operation manual
1. Connect IBM-AT compatible PC with AKD4353 by 10-line type flat cable (packed with AKD4353).
Take care of the direction of 10pin Header (Refer to manual of AKD4353).
2. Start up “WINDOWS 95” or “WINDOWS 98”.
3. Insert the floppy-disk labeled “AKD4353 Control Program ver 2.0” into the floppy-disk drive.
4. Set up “MS-DOS” from start menu.
5. Change directory to the floppy-disk drive(ex.a:) at MS-DOS prompt.
6. Type “ak4353”.
7. Then follow the displayed comment (See the following).

2) If you input “R” or “r”, this program writes default data to all register addresses.
3) If you input “T” or “t”, current register map is displayed.
4) If you input “I” or “i”, this program increment data of current address by 1 (only for addr=03H or 04H). You can
increment ATT value by 1step.
5) If you input “D” or “d”, this program decrement data of current address by 1 (only for addr=03H or 04H). You can
decrement ATT value by 1step.
6) If you input “S” or “s”, this program is terminated.
