The USB Type-C connector has significant adoption with standards like USB, DP, and Thunderbolt. This session will look at preparing to test the next-generation variant of USB - USB4. USB4 will transmit and receive on all 4 lanes of the Type-C connector in parallel, with bonded rates of 40Gbps in each direction for a 80Gbps link. As these signals get sent through even longer passive cables, specialized Transmitter and Receiver techniques are required to preserve Signal Integrity. We will review these new Equalization requirements, Signaling technologies, new measurement methodologies, and ultra-low noise test instrument to properly characterize these very high-speed signals.
