Figure 34 shows the system connection diagram. An evaluation board is available which demonstrates application
circuits, the optimum layout, power supply arrangements and measurement results.
Notes:
MS0097-E-01
- “C” depends on the crystal.
- AVSS, DVSS and PVSS must be connected 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 AK4586 with
performance.
