Quickly Bring Up USB4 Type-C Link

Numerous Type-C, USB-Power Delivery (USB-PD), and high-speed handshake standards make establishing a Type-C link a complex task. That’s why it is critical to ensure that all Type-C technologies communicate correctly, particularly with USB4. The USB4 interface Rx / Tx electronic design is complicated by factors that include the 20 Gbps signaling rate, cross talk from three other lanes running at the same speed, a bonded aggregate bit rate of 40 Gbps, and the need for optimization over a low-cost passive cable.

This use case demonstrates tools needed to debug and optimize a USB4 Type-C link. You can accomplish this task by connecting to a device under test, triggering on low-speed packets, capturing / decoding sideband and high-speed signals, and viewing the time-correlated waveforms to determine potential signal integrity issues.
