3. Jitter Tolerance
Figure 32 shows the jitter tolerance to ILRCK for AK4122. The jitter frequency and the jitter amplitude shown in Figure 32
define the jitter quantity. When the jitter amplitude is 0.01Uipp or less, the AK4122 operate normally regardless of the jitter
frequency.
MS0267-E-03
(1) Normal operation
(2) There is a possibility that the distortion degrades. (It may degrade up to about −50dB.)
(3) There is a possibility that the output data is lost.
Note:
- The jitter amplitude is for ILRCK and 1UI (Unit Interval) is one cycle of ILRCK. When FSI = 48kHz, 1UI is
1/48kHz = 20.8µs.
