EVALUATION BOARD MANUAL
n Operation sequence
1) Set Up the power supply lines
[AVDD]
(Orange) = 2.0 ∼ 3.3V (typ. 2.5V, AVDD pin)
[DVDD]
(Orange) = 1.8 ∼ AVDD (typ. 2.5V, DVDD pin, U2:74LCV541, U5:74LCV07A)
[MVDD]
(Green) = 2.4 ∼ 3.3V (typ. 2.7V, MVDD pin)
[VCC]
(Red) = 5.0V (for digital logic except the AK5356)
[AVSS]
(Black) = 0V
[DVSS]
(Black) = 0V
[MVSS]
(Black) = 0V
Each supply line should be distributed from the power supply unit.
DVDD and AVDD must be the same voltage level.
When the regulator (3V output) is used, “AVDD” terminal supplies “5V”.
2) Set up the evaluation mode, jumper pins and DIP switches. (See the following)
3) Power on
The AK5356 and AK4103 should be reset once bringing SW1 = SW3 = “L” upon power-up.
n Evaluation Mode
Applicable Evaluation Mode
(1) Evaluation of A/D using DIT (Optical Link) <Default Setting>
(2) All interface signals including master clock are fed externally.
(3) Evaluation of A/D using DIT at MCLK = 384fs
