Notes:
- “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
performance.
- In case of coaxial input, ground of RCA connector and terminator should be connected to PVSS of the AK4683
with low impedance on PC board.
