14. Jitter Tolerance
Figure 20 shows the jitter tolerance to ILRCK and IBICK. The jitter quantity is defined by the jitter
frequency and the jitter amplitude. When the jitter amplitude is 0.02UIpp or less, the AK4133 operates
normally regardless of the jitter frequency.

Figure 20. Jitter Tolerance
This is an evaluation result with synchronous input data to ILRCK and IBICK when jitter is added.
The area (1) and (2) border is the the jitter amplitude of ILRCK just before THD+N degradation starts.
Please use the jitter amplitude of the area (1).
(1) Normal Operation
(2) There is a possibility that the output data is lost.
1UI (Unit Interval) is one cycle of IBICK. 1[UIpp] = 1/48kHz = 20.8μsec when FSI is 48kHz.
