GENERAL DESCRIPTION

AKD5367A-A is an evaluation board for the digital audio 24bit 96kHz A/D converter, AK5367A. The

AKD5367A-A includes the input circuit and also has a digital interface transmitter. Further, the

AKD5367A-A can achieve the interface with digital audio systems via optical connector. And it can

achieve the direct interface with AKEMD’s D/A converter evaluation boards of via 10-line flat cable.

Table 1. Power Supply Lines

Note 1. 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 AK5367A and AK4104 should be reset once bringing SW1 and SW2 = “L” and return it to “H” to upon

power-up.

Evaluation Mode

(1)Slave mode

When evaluating the AK5367A using the AK4104, the setting of the AK5367A’s audio interface format

should be the same as the AK4104’s format. When the AK4104 is used, the audio interface format is the

default setting of 16/24bit I2S compatible. Therefore, set DIF bit=”1” to agree with the AK4104’s format.

(1-1) A/D evaluation using AK4104 DIT function

PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and it is output through optical

connector (TOTX141). It is possible to connect AKEMD’s D/A converter evaluation boards on the

digital-amplifier. The clock can be generated from crystal oscillator X1 or be input from J11 (BNC) or PORT2

(ROM).
