Layout Pattern Example
AK4554 requires careful attention to power supply and grounding arrangements to optimize performance.
(Please refer to AKD4554 Evaluation Board layout pattern.)
1.
VDD pin should be supplied from analog power supply on system, and VSS pin should be connected to analog
ground on system. The AK4554 is placed on the analog ground plane, and near the analog ground and digital ground
split. And analog and digital ground planes should be only connected at one point. The connection point should be
near to the AK4554.
2.
VDD pin should be distributed from the point with low impedance of regulator etc.
3.
The series resistors are prevent on the clock lines to reduce overshoot and undershoot. To avoid digital noise
coupling to analog circuit in the AK4554, a 10pF ceramic capacitor on MCLK pin is connected with digital ground.
4.
0.1
μ
F ceramic capacitors of VDD-VSS pins and VCOM-VSS pins should be located as close to the AK4554 as
possible. And these lines should be the shortest connection to pins.
