Abstract
A method of interfacing circuits operating in different voltage domains includes receiving a first signal with a first circuit operating in a first voltage domain and generating a second signal with a second circuit operating in a second voltage domain. The second signal is level shifted between the first and second voltage domains with a level shifter and synchronized with the first signal with a third circuit operating in the first voltage domain.
