Description :

The MIPI D-PHY-based mobile computing designs create significant challenges -- fast, multi-lane bursts of high-definition images, multi-bus integration, HS/LP signal switching, and accelerating development cycles all add pressure to development teams.

The U4421A MIPI D-PHY Exerciser/Analyser addresses these challenges by combining a true protocol analyser -- protocol-aware triggering, filtering, storage qualification and analysis, the first “raw” view of data (an oversampling of states that lets you see they “why” of your protocol, instead of the “what”), and a full-featured protocol exerciser -- all in one instrument.

The U4421A Exerciser/Analyser is an AXIe-based module that can reside in a 2-slot or 5-slot mainframe. Multiple mainframes and modules can be combined to give you views into multi-bus MIPI systems (combining DSI and CSI-2), or with other AXIe modules, including PCIe, DDR, and HDMI bus analysis. The system can be controlled by an external PC or with an M9536A AXIe embedded controller.

The system’s flexibility is not limited to mainframe configuration. There are many probing options to accommodate a wide variety of cables , vias, traces, sockets, and high-density headers. Expanded lanes and memory, protocol support, and image analysis are all optional and can be upgraded at any time.
