Automotive USB poses reliability challenges
Design How-To  
11/2/2010   Post a comment
In consumer electronics, USB is the most popular interface technology. But for USB to capture "the pole position" among competitive technologies for automotive use, questions of quality must be answered.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
