= 4.75 ∼ 5.25V (typ. 5.0V, for AVDD, TVDD of AK5366VR)
= 3.0 ∼ 5.25V (typ. 3.3V, for DVDD of AK5366VR)
= 3.0 ∼ 5.25V (typ. 3.3V, for VCC of 74LVC541)
= 5V (for VCC of logic circuit of digital part)
= 0V (for analog ground)
= 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 AK5366VR and AK4103 should be reset once bringing SW2 = “L” upon power-up.
„ Evaluation mode
(1) Slave Mode
When evaluating the AK5366VR using the AK4103, the setting of the AK5366VR’s audio interface format should
be the same as the AK4103’s format. The DIF setting of the AK5366VR (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 AK5366VR’s
audio interface format, refer to AK5366VR’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).
