A LOW-POWER TYPE-C RECEIVER WITH HIGH IDLE NOISE AND DC-LEVEL REJECTION

摘要

Techniques for low-power USB Type-C receivers with high DC-level shift tolerance and 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 receive data from an incoming signal on the CC line even when the incoming signal has more than 250mV of DC offset with respect to local ground, and to reject the incoming signal even when the incoming signal includes noise with a magnitude of more than 300mVpp.
