Why should jitter be minimized in CPRI fronthaul? - frequency accuracy

In this post, we will talk about “jitter” introduced in the fronthaul network of LTE C-RAN. As shown in the figure on the right, jitter refers to the skew or variation in time or phase of a digital signal exchanged between communication systems. This jitter can eventually cause errors during the data and clock recovery process at RRH. Then, why should we be worried about jitter...
