20-300 MHz Frequency Generator with-70 dBc Reference Spur for Low Jitter Serial Applications

Catherine Dehollain, Gürkan Yilmaz

This paper presents a frequency synthesizer based on a phase locked loop (PLL) targeting low jitter applications. The frequency generator covers a range wider than a decade, more explicitly from 20 to 300 MHz. Thanks to a 4-stage ring oscillator, it can pr ...

ns-level time transfer over a microwave link using the PTP-WR protocol

Pierre-André Farine, Cyril Botteron, Jean-Pierre Aubry, Mathieu Paul Joseph Carlos Rico

Today it is possible to achieve sub-ns level time synchronization on a wireline network while only us-level synchronization can be achieved on a wireless (microwave) link. In this paper we will, first, study the performances of different time synchronizati ...
