Abstract
Techniques for low-power USB Type-C receivers with high noise rejection are described herein. In an example embodiment, a USB-enabled device comprises a receiver circuit coupled to a Configuration Channel (CC) line of a USB Type-C subsystem. The receiver circuit is configured to reject the incoming signal even when the incoming signal includes noise with a magnitude of more than 300 mVpp, and to operate in the presence of a VBUS charging current that is compliant with a USB-PD specification.
