摘要：
Techniques are provided for transmitting signals through a differential interface between circuits in different power supply domains. A driver circuit in a first power supply domain converts single-ended signals into differential signals. The driver circuit then transmits the differential signals to a receiver circuit in a second power supply domain. The receiver circuit converts the differential signals back into single-ended signals for transmission to circuit elements in the second power supply domain. The differential interface reduces the transmission of noise between circuit elements in the first power supply domain and circuit elements in the second power supply domain.
