Evaluation Board Manual
Operation sequence
1) Set up the power supply lines.
[AVDD] (red) = 4.75
∼5.25V : for AVDD of AK5366 (typ. 5.0V)
[TVDD] (orange)= 3.0
∼5.25V : for DVDD of AK5366 (typ. 3.3V)
[D3V] (orange)= 3.0 ∼5.25V : for 74LVC541 (typ. 3.3V)
[VCC] (red) = 5V : for logic
[AGND] (black) = 0V : for analog ground
[DGND] (black) = 0V : for logic ground
Each supply line should be distributed from the power supply unit.
D3V and TVDD must be same voltage level.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK5366 and AK4103 should be reset once bringing SW2 = “L” upon power-up.
Evaluation mode
(1)Slave Mode
When evaluating the AK5366 using the AK4103, the setting of the AK5366’s audio interface format should be the
same as the AK4103’s format. The DIF setting ofthe AK5366 (No.1 of SW1 (I2C) in parallel mode, DIF bit in serial
mode) should be the same as the DIF setting of the AK4103 (No.1 of SW3). About the AK5366’s audio interface
format, refer to AK5366’s datasheet. About the AK4103’s audio interface format, see Table3.
(1-1) A/D evaluation using DIT function of AK4103
PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and which is output through
optical connector (TOTX176). It is possible to connect AKM’s D/A converter evaluation boards on the
digital-amplifier which equips DIR input. Nothing should be connected to PORT2 (ROM). In case of using
external clock through a BNC connector (J13), select EXT on JP8 (CLK) and short JP6 (XTE) and open JP9
(EXT).
