A method for communicating across first and second frequency domains of an
integrated microchip is provided. The method initiates with determining a
clock ratio between the first frequency domain and the second frequency
domain. The first frequency domain is associated with a faster clock
cycle. Then, a synchronizing signal based upon the clock ratio is
generated. The synchronizing signal coordinates communication of data
between the first and second frequency domains. Next, the data is
transferred between respective frequency domains according to the
synchronizing signal. A microchip and a system enabling synchronous data
transfer across different frequency domains are also provided.
