Title:
APPARATUS FOR SYNCHRONIZING A DATA HANDOVER BETWEEN A FIRST CLOCK DOMAIN AND A SECOND CLOCK DOMAIN
Document Type and Number:
WIPO Patent Application WO/2012/160105
Kind Code:
A9
Abstract:
Embodiments of the present invention provide an apparatus for synchronizing a data handover between a first clock domain and a second clock domain. The apparatus includes a calculator, a synchronization pulse generator, a phase information provider and a feedback path. The calculator is clocked with a clock of the first clock domain and configured to provide synchronization pulse cycle duration information describing a temporal position of a synchronization pulse at a clock of the second clock domain. The synchronization pulse generator is clocked with the clock of the second clock domain and configured to generate the synchronization pulse such that the synchronization pulse is located at the temporal position described by the synchronization pulse cycle duration information. The phase information provider is clocked with the clock of the second clock domain and configured to provide a phase information describing a phase relation between the synchronization pulse and the clock of the first clock domain. The feedback path is configured for feeding back the phase information to the calculator. In addition, the calculator is configured to adjust the synchronization pulse cycle duration information based on the phase information.
