Increasing robustness of source synchronous links by avoiding write pointers based on strobes

A source synchronous scheme in which data from one clock domain is synchronized to a clock of a second clock domain. Using a more reliable clock of the second domain to control and adjust the alignment after the data is latched in allows more robust performance to maintain correctly ordered data. In...

Summary:A source synchronous scheme in which data from one clock domain is synchronized to a clock of a second clock domain. Using a more reliable clock of the second domain to control and adjust the alignment after the data is latched in allows more robust performance to maintain correctly ordered data. In this manner, a write pointer based on strobe signal(s) from the first clock domain may be avoided.
