U4431A Protocol Analyzer for MIPI™ M-PHY Interfaces

Product Description 

Deep insight to help you win the race to M-PHY 

The MIPI™ M-PHY standards are the backbone of nextgeneration mobile computing designs. Because these designs are replacing desktop PCs in many applications, these architectures are much faster and more complex than in the past. The increasing demand for bandwidth has driven the expansion of the M-PHY specification to include four-lane, 6.0-Gbs options. The U4431A offers up to 16 GB of analysis memory on each lane, allowing designers to capture tens of seconds of system traffic, even at these high speeds. In addition, the Keysight U4431A offers “Raw Mode,” a feature that lets designers see the time-correlated 8b/10b data that underlies each protocol. These states can be displayed as a waveform or listing, providing insight into how a packet is formed at the physical layer.
