Grounding and Power Supply Decoupling
The AK4121A requires careful attention to power supply and grounding arrangements. VDD are usually supplied from
the system’s analog supply.
AVSS and DVSS of the AK4121A must be connected to the analog ground plane.
System analog ground and digital ground should be connected together as close as possible to where the supplies are
brought onto the printed circuit board. Decoupling capacitors especially a 0.1
μ
F ceramic capacitor for high frequency
noise should be placed as near to VDD as possible.

PLL Loop-Filter
The C1 (4.7
μ
F) and R (560ohms) should be connected in series and attached between FILT pin and AVSS in parallel
with C2 (1.0nF). A Care should be taken to ensure that noise on the FILT pin is minimized.
