Title:
SYSTEM FOR COHERENT DISTRIBUTION OF OSCILLATOR SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/201260
Kind Code:
A1
Abstract:
A local oscillator (LO) distribution system is described. The LO system includes a plurality of phase-locked loop (PLL) modules coupled to each other in a one-way, circulant coupling topology. Each PLL module receives a reference clock signal and outputs an output LO signal. Each PLL module provides a local LO signal to an adjacent downstream PLL module, where the local LO signal is a frequency divided version of the output LO signal. Each PLL module receives an adjacent LO signal from the adjacent upstream PLL module. The phase of the output LO signal is made to be coherent with the phase of the reference clock signal and the phase of the adjacent LO signal, using a feedback loop.
