Title:

DEVICE AND METHOD FOR SUPPORTING CLOCK TRANSFER IN MULTIPLE CLOCK DOMAINS

Document Type and Number:

WIPO Patent Application WO/2017/152412

Kind Code:

A1

Abstract:

A device and a method for supporting clock transfer in multiple clock domains. The device comprises: N phase frequency detectors, N filters, N clock reconstructors, and N clock domain interfaces, N being an integer greater than or equal to 2, the N clock domain interfaces corresponding one-to-one to the N phase frequency detectors, the N filters, and the N clock reconstructors respectively, the N phase frequency detectors being connected to N clock sources respectively, and at least two clock sources among the N clock sources being different. By means of transferring common clock signals, digitized phase difference information and frequency difference information, the described device is able to reconstruct a plurality of different clock signals, and apply same to the clock domain interfaces of the respective clock domains, thereby flexibly adapting to a plurality of different clock domains, simultaneously supporting clock transfer in multiple clock domains with a single device, flexibly satisfying a user's needs, without adding or changing the device.
