GENERAL DESCRIPTION

The AKD4363 is an evaluation board for AK4363, 96kHz 24bit D/A converter with PLL. The AKD4363 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 AK4363.

Evaluation board for AK4363

(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

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).

Operation sequence

1) Set up the power supply lines.

[AVDD] (red)

= 2.7

5.5V

: for AVDD of AK4363

[3V] (orange)

= 2.7

5.5V

: for DVDD of AK4363

[5V] (red)

= 3.4

5.5V

: for logic

[AGND] (black) = 0V

: for analog ground (including AVSS and DVSS of AK4363)

[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 AK4363 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 AKD4363. Take care of the direction of connector. There is a mark at 1pin. The direction of PORT2 is as
the following figure.

SDA/CDTI

SDA(ACK)

5) Set up the software.

Use the software named "AKD4363 Control Program" packed with the AKD4363.

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 AKD4363 to AKD43XX and LRCK, BICK, SDTI are supplied from AKD43XX to
AKD4363. In case of using external clock through a BNC connector (J4), select "BNC" on JP14 (CLK) and
short JP15 (XTE).

3) DIR(CS8414)

PORT4 (TORX174) is used for the evaluation using such as test disk. The DIR generates MCKI, BICK,
LRCK, SDTI from the received data through optical connector. In this case, the EXT bit of AK4363 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).

Serial control mode

The AK4363 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 AKD4363.

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).
