In this work we study the effects of double-frequency jitter in OWMS (one way master-slave) chain network for clock distribution systems. The master-slave architecture considers the slave nodes as phase-locked loops (PLL) and nonlinearity in phase detection generates the double-frequency jitter. A network is modeled and simulated in order to compare the results with ITU-T standards.
The main strategy used for distributing clock information along telecommunication synchronous networks is the master-slave (M-S), i.e., a well determined node provides a precise clock signal distributed to the other nodes that need to recover it using phase-locked loops (PLL). In spite of the PLLs being equipped with low pass filters, the recovered clock signal always contains second harmonic components...
