Multi-access stable radio frequency phase dissemination for 100 km fiber-optic loop link is achieved based on single optical source. Phase jitter of 2.4 GHz signal at the accessing node is reduced to 1.57 ps/1.76 ps.
A 10 GHz all digital frequency synthesizer (ADPLL) with dynamic digital loop filter is presented. Governed by a proposed locking process monitor (LPM), the digital loop filter is automatically reconfigured during the frequency acquisition and phase tracking process. The loop bandwidth is also self-adjusted during the locking process so as to achieve fast lock and low noise simultaneously. A skew-compensated...
A testbed based on European Cost-239 topology is constructed to demonstrate the transmission performance of MPLS-TP network. By introducing streaming media traffic, two factors are given with numerical results to show their influences on transmission.
ADPLL frequency synthesizers have recently drawn significant research attention as the technology paradigm shifts into the nanometer CMOS arena. They circumvent several design issues that conventional charge-pump-based PLLs encounter, including capacitor leakage, current mismatch, and limited dynamic range. Furthermore, they benefit from replacing the bulky passive loop filter by a more cost-effective...
