MOBILE ASIA EXPO, Shanghai, China, June 22, 2011– MIPI Alliance today announced the next generation of two specifications designed to dramatically improve data transport performance in mobile devices.  M-PHY v2.0 offers an optimized scalable physical layer with bandwidth speeds reaching 2.9Gbps per lane. The UniPro v1.41 updates the specification, focusing on the M-PHY physical layer to provide a unified, layered protocol stack. Combined, these two specifications deliver the highest performance and most power efficient data transport interface technology available today. M-PHY v2.0 has been adopted and is available for MIPI Alliance members. UniPro v1.41 is scheduled for adoption by the end of July 2012. For more information, go to

In addition to supporting smartphones and full-function phones, both M-PHY and UniPro are suitable for other applications including tablets/netbooks, digital  cameras, high speed memory storage and multimedia devices. The benefits of these high bandwidth, high performing interface technologies also address the needs any portable consumer electronics device which must process large amounts of data with a low power threshold.

M-PHY GEAR 2 Delivers Key Features

M-PHY v2.0 is a high bandwidth serial interface with an exceptionally wide data rate range spanning 10kbps to near 6Gbps. Bandwidth can be scaled based on the application needs, by selecting from several available transmission rates or by scaling up to multiple transmission lanes, making M-PHY a very flexible physical layer. Multiple transmission modes plus a low energy per bit threshold rate equals significant power efficiency. In addition, M-PHY is optical friendly, providing mobile product designers with  an optional low-complexity electro-optical signal conversion and  transport for additional assembly and reliability benefits.

The M-PHY physical layer is designed as the primary interface for MIPI’s transport layer UniPro. This connection is accomplished via UniPort-M, the actual port coupling the two layers. By specifying a dedicated port, MIPI can insure that high performance data transport is maintained.

UniPro Simplifies Device Interconnection

Building on the M-PHY physical layer, UniPro v1.41 leverages a stack of protocol layers, serving as a high performance processing pipeline for data units. It is suitable for a wide range of component types including application processors, co-processors and modems, as well as different types of data traffic. UniPro is scalable from a single link to network architecture. By simplifying the interconnection between disparate devices, UniPro reduces time-to-market and design costs.

“The MIPI Alliance M-PHY and UniPro specifications are becoming widely adopted, both by individual companies and organizations such as JEDEC,” said Joel Huloux, Chairman of the Board for MIPI Alliance. “We are very pleased to see such rapid progress in advancing the technical capabilities of these specifications.”

These specifications were developed by the MIPI Alliance PHY and UniPro work groups, comprised of industry experts spanning the mobile device ecosystem. Their system level approach, combined with interaction across groups, has resulted in these optimized specifications.
