AKD4380
Evaluation board Rev.A for AK4380
GENERAL DESCRIPTION
The AKD4380 is an evaluation board for AK4380, which is 96kHz sampling 24Bit∆ΣDAC.
AKD4380 has the interface with AKM’s wave generator using ROM data and with AKM’s A/D converter
evaluation boards. Therefore, it is easy to evaluate the AK4380. The AKD4380 also has the digital audio
interface and can achieve the interface with digital audio systems via opt-connector or RCA connector.

Evaluation board for AK4380
FUNCTION
• Compatible with 2 types of interface
-Direct interface with AKM’s A/D converter evaluation boards (539X,535X)
,and direct interface with a signal generator (AKD43XX)
- On-board CS8414 as DIR which accepts optical or RCA input.
• BNC connector for an external clock input by 10 pin Hearder.

„ Analog output
Analog signal is output through BNC connectors on the board. And the output level of AK4380 is 3.45Vpp.
„ Operation sequence
1) Set up the power supply lines.
[VA] (red)
= 4.5 ∼ 5.5V
[VD] (red)
= 4.5 ∼ 5.5V
[AGND] (black) = 0V
[DGND] (black) = 0V
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 AK4380 should be reset once bringing upon power-up
„ Evaluation mode
Applicable evaluation modes
1) DIR (Optical Link and RCA) (default)
2) Using ROM data (AK43XX)
3) Using AKM’s evaluation board for ADC
4) Feeding all signals from external
1) DIR(Optical Link)
PORT3(TORX176) or J3(RCA) is used. All clock are supplied from CS8414(DIR). DIR generates MCLK,
BICK, LRCK and SDATA from the received data through optical connector (TORX176) or RCA connector.
Used for the evaluation using CD test disk. Nothing should be connected to PORT2. In case of using optical
connector (TORX176), select “OPT” on JP14(DIR/RX). In case of using RCA connector, select “RX”.

2) Ideal sine wave generated by ROM data
Connect the AKD43XX with PORT2(ADC/ROM). AKD4380 sends MCLK to AKD43XX, and receives LRCK,
BICK and SDATA. In case of using external master clock through a BNC connector, select “BNC” on
JP12(MCLK) and short JP13(XTE).

3) Using AKM’s evaluation board for ADC
To evaluate AK4380 with analog input, the AKM’s evaluation board for ADC can be used. MCLK, BICK and
LRCK are supplied from clock generator on the AKD4380, and analog signal is A/D converted and send to
AKD4380 through PORT2(ADC/ROM). In case of using external master clock through a BNC connector, select
“BNC” on JP12(MCLK) and short JP13(XTE).

• AKM assumes no liability for infringement of any patent, intellectual property, or other right in the

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
