Abstract
A system for synchronizing a functional reset between first and second clock domains that operate on first and second clock signals, respectively. The system includes first, second and third synchronizer flip-flops that operate on the second clock signal. The first synchronizer flip-flop receives a functional reset signal generated by the first clock domain at its reset terminal and generates a low output signal. The low output signal causes the second synchronizer flip-flop and subsequently the third synchronizer flip-flop to generate low output signals at positive edges of the second clock signal. The low output signal generated by the third synchronizer flip-flop is used to reset the second clock domain.
