AVDD for AK5367A,
Regulator T1.
This connector must be connected.
+5V
DVDD
Red
+3.0~+3.6V
DVDD for AK5367A
This connector is used when DVDD of AK5367A is
supplied from DVDD connector without regulator T1.
In this case, JP2 should be open. (Default)
+3.3V
CVDD
Red
+3.0~+3.6V
CVDD for AK5367A
This connector is used when CVDD of AK5367A is
supplied from CVDD connector without regulator T1.
In this case, JP3 should be open. (Default)
+3.3V
D3V Red
+3.0~+3.6V
AK4104,
Logic circuit
This connector is used when power of AK4104 and
logic circuit is supplied from +3.3V connector without
regulator T1. In this case, JP4 should be open. (Default)
+3.3V
AGND
Black
0V
Analog ground
This connector must be connected.
0V
DGND Black
0V Digital
ground
This connector is used when DGND is supplied
separately from AGND. In this case, JP1 should be
open. (Default)
0V
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).
