Abstract
The present invention provides a highly reliable synchronizer which provides excellent synchronization without using complicated PLL or DLL circuitry, which is simple to test, which is easily adaptable to systems which use bit-sliced data, and which does not require large chip area. The synchronizer is comprised of a first stage, a data capture circuit, preferably comprised of pair of master-slave flip-flops, that is electrically coupled to a second stage, a data selection circuit that preferably includes a FIFO comprised of N transparent latches that are electrically coupled to a multiplexer. The lack of complexity of the synchronizer design makes it smaller, faster, easier to test, and less prone to design error and manufacturing limits.
