Table 1. Set up power supply lines
* Setting of Power Supply “DVDD”: JP10 (DVDD-REG)
Open: It supplies “DVDD” from the outside to right pin.
Short: It supplies “DVDD” from the Regulator (3.3V) <default>.
Each supply line should be distributed from the power supply unit.
3.3V is supplied to AK4373 via the regulator.
2) Set up the evaluation mode, jumper pins. (See the followings.)
3) Power on.
The AK4373 and AK4116 should be resets once bringing SW1 (DAC/DIR-PDN) “L” upon power-up.
„ Evaluation mode
When evaluating the AK4373 using the PORT1 (AK4116), it is possible to use the initial setting of the audio
interface format (24bit MSB justified). The AK4116 operates at fs of 32kHz or more. If the fs is slower than
32kHz, any other evaluation mode should be used.
When inputting the data from the PORT2, the AK4373’s audio interface format should be set to correspond
the input data’s audio interface format. Refer to the AK4373’s datasheet.
Applicable Evaluation Mode
(1) PLL Master Mode
(2) PLL Slave Mode
(2-1) PLL Reference Clock: MCKI pin
(2-2) PLL Reference Clock: BICK or LRCK pin
(3) External Slave Mode
(3-1) Evaluation using DIR (Optical Link) of AK4116 <default>
(3-2) Evaluation connecting AKD4373 with external DSP
(4) External Master Mode
