AKD4380
Evaluation board Rev.A for AK4380
GENERAL DESCRIPTION The AKD4380 is an evaluation board for AK4380, which is 96kHz sampling 24BitDAC. 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. n Ordering guide
AKD4380 --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.

n Analog output
Analog signal is output through BNC connectors on the board. And the output level of AK4380 is 3.45Vpp.
n 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 n 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". JP3 BICK JP4 LRCK JP9 SDTI JP10 DIR_DATA JP11 DIR JP12 MCLK JP13 XTE

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). JP3 BICK JP4 LRCK JP9 SDTI JP10 DIR_DATA JP11 DIR JP12 MCLK

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). JP3 BICK JP4 LRCK JP9 SDTI JP10 DIR_DATA JP11 DIR JP12 MCLK JP13 XTE
