摘要:
A circuit includes a power supply terminal and a clock parsing circuit configured to produce multiple clock signals having a common clock period and different phases. The circuit further includes a plurality of digital circuits coupled to the clock parsing circuit and the power supply terminal. Each digital circuit includes an input to receive data and logic to process the data. Each digital circuit is responsive to a phase associated with a respective clock signal of the multiple clock signals to draw current from the regulated power supply terminal to process the data to produce a data output. Additionally, the circuit includes an output timing management circuit coupled to each of the plurality of digital circuits and configured to control data outputs of each of plurality of digital circuits to prevent timing violations at one or more destination circuits.
