D-PHY offers per-lane speeds from 80 Mb/s M-PHY extends that up to 6 Gb/s per lane. Both D-PHY and M-PHY support data transmissions over 30 cm of PCB trace or microcoax. He is also reaching out to handset vendors, who would not directly engage with UNH-IOL but could drive their component suppliers to use the lab's services to ensure their devices comply.īaldman said the next steps with regard to the MIPI Allicance will center on the M-PHY. The goal of the collaboration among the MIPI Alliance, UNH-IOL, and test and measurement equipment suppliers such as Agilent is to facilitate the production of low-cost mobile devices, including smartphones, tablets, and ultrabooks that offer improved performance, higher resolution images, and superior video quality.īaldman said many of the 70,000 attendees may not know what an oscilloscope is, but he reported active interest in the demonstrations from hardware engineers and component designers in attendance. Combined with the UNH-IOL’s custom D-PHY GUI software, the Agilent platform provides the ability to capture and analyze D-PHY signaling in accordance with the UNH-IOL D-PHY Transmitter Physical Layer Conformance Test Suite. The demonstrations at MWC focus on D-PHY, the current standard for physical layer signaling in camera and display interface applications.Īt the show, Baldman, who also serves as vice chair of the MIPI Alliance’s PHY Working Group and co-chair of the Conformance Test Specification Subgroup within the MIPI Alliance, is using an Agilent Infiniium MSO9404A oscilloscope to perform testing on mobile components, including ones based on Synopsys’ DesignWare MIPI D-PHY IP solution. Reporting from the show floor, Andy Baldman, senior technical staff member at the UNH-IOL, said booth visitors are participating in demonstrations of the rigorous conformance testing performed on the mobile-device components that implement MIPI specifications. The UNH-IOL and Agilent Technologies are co-hosting the MIPI Test Corner, a section of the MIPI Alliance booth at the MWC. The University of New Hampshire Interoperability Laboratory (UNH-IOL) is demonstrating its MIPI testing services for mobile device component suppliers this week at Mobile World Congress 2013 in Barcelona.
