SYSTEM DESIGN
Figure 9 shows the system connection diagram. An evaluation board[AKD4317] is available which
demonstrates the optimum layout, power supply arrangements and measurement results.
Figure 9 . Typical Connection Diagram
Notes:
- LRCK=fs, MCLK=256fs at CKS="L", MCLK=384fs at CKS="H".
- If the above serial mode control is not used, CS should be held "H".
- Power lines of AVDD and DVDD should be distributed separately from the point with low
impedance of regulator etc.
- When AOUT drives some capacitive load, some resistor should be added in series between
AOUT and capacitive load.
- The capacitor value on VCOM depends on low frequency noise level of power supply.
- All input pins except pull-down pins(DIF0,DIF1,DEM,TST1) should not be left floating.
