Title:
SENSING SYSTEM, RELATED APPARATUS, AND METHOD FOR OBTAINING WORKING CLOCK SIGNAL
Document Type and Number:
WIPO Patent Application WO/2022/198434
Kind Code:
A1
Abstract:
The present application discloses a sensing system, a related apparatus, and a method for obtaining a working clock signal. The sensing system comprises at least one chip cascade branch; in the chip cascade branch, a clock integration circuit of each sensing chip integrates the received working clock signal to obtain a stable clock signal to be subjected to frequency division that has a relative high frequency, and then a frequency division circuit performs frequency division processing on said clock signal to obtain a working clock signal required by a next-stage sensing chip; in the cascade structure, a clock source only needs to satisfy the driving requirement of a first-stage sensing chip, and the working clock signal required by each of other sensing chips is provided by a previous-stage sensing chip, such that the problem that the number of sensing chips connected in series in the chip cascade branch is limited by the driving capability of the clock source is solved, and the applicability of the sensing system is widened.
