• Description: Asynchronous Multi-channel Audio Codec With Dir/t
• Manufacturer: AKM Semiconductor, Inc.

Figure 50 shows the system connection diagram. The evaluation board is available which demonstrates application
circuits, the optimum layout, power supply arrangements and measurement results.
Notes:
MS0427-E-02
- “C” depends on the crystal.
- AVSS, DVSS, PVSS and HVSS must be connected to the same analog ground plane.
- Digital signals, especially clocks, should be kept away from the R pin in order to avoid an effect to the clock jitter
- In case of coaxial input, ground of RCA connector and terminator should be connected to PVSS of the AK4683
performance.
