MIPI M-PHY test solution announced before specification is released

Market news |
As the Mobile Industry Processor Interface (MIPI) Alliance is finalizing the M-PHY specification to allow development of faster, more reliable high-speed interfaces for mobile devices, Agilent Technologies has announced a MIPI M-PHY test solution for debugging and validating all layers of M-PHY devices, including physical and protocol layers, at speeds up to 5.8 Gb/sec.

M-PHY technology supports a broad range of applications, including interfaces for monitors, cameras, audio and video equipment, memory, power management and communication between baseband and RFIC components.

The Agilent solution consists of oscilloscopes, protocol analyzers and exercisers, and bit error-rate testers (BERTs) using custom M-PHY stimulus software. Each instrument comes with custom M-PHY-ready software to support design teams through the entire product design process.

“Working closely with customers developing early M-PHY-based silicon allowed us to provide robust M-PHY test solutions even before the final specification became available,” said Roland Scherzinger, Agilent’s MIPI program manager. “In addition, we were happy to share our experience in testing high-speed serial technologies in the MIPI workgroups, ensuring robust M-PHY specifications in terms of signal integrity and testability.”

Accurate and automated MIPI M-PHY receiver testing is supported by Agilent’s ParBERT 81250A for multi-lane testing and J-BERT N4903B for single-lane testing. Although the MIPI M-PHY receiver test specifications have not been finalized yet, engineers can use these bit error-ratio testers for accurate M-PHY receiver tolerance testing in a pattern generator or full BERT configuration in conjunction with N5181/2A, E4438C and 81150A signal generators.

The company claims that the N5990A-165 MIPI M-PHY/ DigRF v4 receiver test automation software saves significant R&D time by automatically calibrating stress conditions and by controlling all test equipment for automated receiver tolerance tests.
