“…Using modelism simulation, when N=5, the two output clock cycles are amplified 33 times, with a high level meter value of 103 and a low level meter value of 722. The phase difference is calculated according to equation (10), indicating that the function of measuring phase through digital dual mixing can be achieved.…”

Precise phase difference measurement is critical for distributed time synchronization systems. Aiming at the problem of how to realize the sub-nanosecond phase difference measurement of the time signal, the digital dual mixer time difference (DDMTD) measurement technology is used to measure the fine transmission delay and the two digital clock phase difference. Given the problem that it is difficult to generate a common clock source with fine frequency changes inside the FPGA chip, the Si5338 chip is used to generate 4 differential clocks, and the communication with the FPGA is completed through the I2C protocol, and the differential signal is converted into a single-ended clock source inside the FPGA as two The common standard frequency of clock signals with the same frequency and different phases, realize the amplification of the phase difference measurement range, making the measurement accuracy reach sub-nanosecond level.

“…They stated that both phase detectors and transceivers have a similar phase noise contribution, which is dominated by flicker phase modulation. M. Rizzi et al have also reported the contribution of 1 Gbps fibre optic transceivers to overall uncertainty, stating that it is practically negligible compared to other uncertainties in the system [ 18 ]. P. Li et al studied the noise-contributing factors and developed a Kalman filter to improve time synchronization accuracy [ 19 ].…”

White Rabbit (WR) is an optical fibre-based time-frequency synchronization technology typically used in timekeeping laboratories for distributing time-frequency signals from a reference clock to distant locations. The accuracy of the received signals at the user end can be affected by random noise processes present in the WR network due to the internal electronic components of WR devices. In this paper, we investigate the presence of random noise processes in the WR network. We then study their statistical properties and model the distribution based on experimentally recorded measurements. According to our study, the probability density function (PDF) follows a Gaussian mixture model (GMM) with varying distribution parameters, and the correlation analysis indicates a strong correlation of the phase noise process over the temporal samples. Furthermore, the developed phase noise models have also been verified by comparing them against additional experimental data. Finally, we present the methodology to generate the phase noise process using computer simulations with the PDF and correlation models developed in this work to help algorithm developers and equipment manufacturers make use of our results.
