T Jitter Tolerance
Figure 8 shows the jitter tolerance to ILRCK for AK4121. The jitter frequency and the jitter amplitude shown in Figure
8 define the jitter quantity. When the jitter amplitude is 0.01Uipp or less, the AK4121 operate normally regardless of
the jitter frequency.
MS0191-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 = 20.8 s.
