Abstract
A synchronization circuit for re-synchronizing data from an input clock to an output clock is presented. The first transparent latch receives data synchronized to an input clock. A second transparent latch receives data from the first transparent latch and outputs data dependent on a delayed output clock which is the output clock delayed by an insertion delay. An output latch receives data from the second transparent latch and synchronizes data to the output clock.
