Jitter Tolerance
Figure 17 shows the jitter tolerance to ILRCK and IBICK for AK4124. The jitter frequency and the jitter amplitude shown
in Figure 17 define the jitter quantity. When the jitter amplitude is 0.01Uipp or less, the AK4124 operate normally
regardless of the jitter frequency.
(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:
- When PLL2-0 = “L/L/L”, “L/L/H”, “L/H/L”, the jitter amplitude is for ILRCK and 1UI (Unit Interval) is one
cycle of ILRCK. When FSI = 48kHz, 1UI is 1/48kHz = 20.8
μ
s.
- When PLL2-0 = “H/*/*” (*: Don’t care), the jitter amplitude is for IBICK and 1UI (Unit Interval) is one cycle of
IBICK. When FSI = 48kHz, 1UI is 1/(64 x 48kHz) = 326ns.
