ABSTRACT:
When communicating data between different voltage and frequency domains, for example chiplets, in an integrated circuit, the data signals can be formatted to compensate for propagation delays and different operating frequencies between the domains, and the signaling voltage level of the formatted data signals can then be changed from the operating voltage of the transmitting domain to the operating voltage of the receiving domain so that the formatted and changed data signals can be transmitted. As such, voltage crossings are combined with frequency crossings, which can have the effect of hiding the voltage shifting within the propagation delays.
