Summary :

The jitter accumulation and its suppression are investigated in the hierarchical Master-Slave synchronization network which applies a king of simple digital signal processing type PLLs, the multiply detecting and averaging PLLs, as the synchronizers. The multiply detecting and averaging means averaging the multiple phase errors detected to produce an output phase correction. The measurement of phase jitter used is its variance and two parameters, named as the normalized relative increment and suppression rate, are introduced to describe the jitter accumulation and its suppression along the hierarchical. It is noted that, the suppression of the systematic jitter accumulation is enhanced proportionally to the averaging times, and much more effect can be obtained on the suppression of the random jitter than the systematic. But for the quantization jitter caused by the quantized output phase correction of synchronizers, the suppression rate is less than -1.76 dB (10 log₁₀ (2/3) dB) for any large averaging times, and thereby it should be made small enough to be negligible.
