ASAHI KASEI
[AKD4562]
(2) Other Jumper pins
1. JP1 (CSN) : Selection of CSN pin
SSB : SSB mode.
AKM : AKM mode.
2. JP2 (SSB) : Selection of SSB mode or AKM mode
OPEN : AKM mode.
SHORT : SSB mode.
3. JP3 (TST) : Selection of TEST pin
OPEN : Normal mode.
SHORT : Test mode.
* Always open.
4. JP4 (GND) : Analog ground and Digital ground
OPEN : Separated.
SHORT : Common. (The connector “DGND” can be open.) <default>
5. JP5 (VT) : D2V and VT
OPEN : Separated. <default>
SHORT : Common. (The connector “VT” can be open.)
6. JP9 (SDTO) : SDTO of AK4562
Always open. It can be short for only evaluation mode “7)”.
7. JP10 (MODE) : Setting mode of CS8412
OPEN : I²S compatible mode.
SHORT : 16 bit LSB justified.
* AKM assumes no responsibility for the trouble when using the above circuit examples.
n Operation sequence
1) Set up the power supply lines.
[VA] (orange) = 2.2 ∼ 3.0V : for VA of AK4562 (typ. 2.5V)
[VT]
(orange)
= 1.8 ∼ 3.0V : for VT of AK4562 (typ. 2.5V)
[D2V] (orange) = 1.8 ∼ 3.0V : for 74LVC541 (typ. 2.5V)
[D5V] (red)
= 3.6 ∼ 5.0V : for logic (typ. 5.0V)
[AGND] (black)
= 0V
: for analog ground
[DGND] (black)
= 0V
: for logic ground
Each supply line should be distributed from the power supply unit.
VT and D2V must be same voltage level.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.)
Note : This evaluation board corresponds to I²S compatible mode for evaluation of A/D.
3) Power on.
The AK4562 and AK4353 should be reset once bringing SW1, 2 “L” upon power-up.
