System for alignment of phase mesh multiple -phase adjustable phase capture, communication device, and, method in a system for alignment of phase -mesh multi -phase adjustable phase capture.

摘要

A system and method for aligning multiple PLLs are described. Does the system comprise a plurality N of PLLs (pll 1? Pl. U) and a plurality N. Of phase detectors (det. 1? Detective No). The plurality N of phase detectors and the plurality N of plywood are connected i n a mesh, so that o n e I -th phase detector (det.I) is configured to receive a n I -th feedback signal (fb -i) generated from the th plywood and o n e (i +1)-th feedback signal (fb -u +i +1) Generated from (i +1)-th plywood,And the n -th phase detector (det -u -n) is configured to receive the first feedback signal (fb -u -1) generated from the first plile and the n -th feedback signal generated from the n -th pl -tile. The one I -th phase detector (detu I) is configured to generate an I -th adjustment sign indicating an I -th phase difference between I -th and (i +1)-th feedback signals to adjust a I -th or (i +1)-th pl -th phase, in which I =1, 2, 3,? N -1 The n -th phase detector (det -u -n) is configured for a n -th adjustment sign indicating a n -th phase difference between the first and N -th signs of feedback.
