U4421A MIPI® D-PHY™ Protocol Exerciser/Analyzer

Data Sheets

The U4421A MIPI D-PHY Analyzer option for CSI-2 and DSI gives you deep insight into your mobile computing designs

Time correlate multiple busses and views. Multiple modules (D-PHY, PCI, DDR, high-speed logic, and HDMI) can be installed in one mainframe, and multiple frames can be connected. Any number of filters and views can be applied. Organize them easily in the overview GUI. Link multiple windows together or track correlated events with markers.

Look deeply into packets with “peel off” tabs. Isolate any packet’s header, or data as a packet payload or individual lanes.

Raw Mode lets you see the “why” behind your protocol. Raw state data that is acquired by the analyzer can be displayed as a time-correlated waveform view.

Get the “big picture” with the Overview tab. Get a count of the various types of traffic in any period of time, including errors; then step through each occurrence with embedded navigation tools.

Isolate events with protocol-aware triggers. Simple drag-and-drop trigger macros can be quickly customized. Or use advanced if-then-else triggers to branch in any direction to up to eight different conditions. Trigger on packet types, errors or into payload data.

Probe any system with three flexible probing options (below). The E5381A differential flying leads let you connect to vias, headers, and traces. The E5404A Soft Touch Pro probe gives you a rugged in-board connection to a small footprint. In addition, UNH-IOL has created an SMA to Soft Touch break-out board that connects directly to their Reference Termination Board, or be used as a generic mid-bus adapter.
