MIPI Alliance has introduced two new updated specifications, M-PHY v2.0 and UniPro v1.41, which will improve data transport performance in mobile devices.
M-PHY v2.0 offers an optimised scalable physical layer with bandwidth speeds 2.9Gbps per lane while the UniPro v1.41 updates the specification, focusing on the M-PHY physical layer to provide a unified, layered protocol stack.
The two new upgraded specifications supports smartphones, full-function phones and are also suitable for other applications including tablets/netbooks, digital cameras, high speed memory storage and multimedia devices.
M-PHY v2.0 is a high bandwidth serial interface with a wide data rate range spanning 10kbps to near 6Gbps. By using this specification, bandwidth can be scaled based on the application needs.
It provides mobile product designers with an optional low-complexity electro-optical signal conversion and transport for additional assembly and reliability benefits.
UniPro v1.41 is built on the M-PHY physical layer and it leverages a stack of protocol layers, serving as a high performance processing pipeline for data units. It is scalable from a single link to network architecture.
It reduces time-to-market and design costs by simplifying the interconnection between disparate devices.
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.
The Mobile Industry Processor Interface (MIPI) Alliance is an open membership organisation that includes several companies in the mobile industry that share the objective of defining and promoting open specifications for interfaces inside mobile terminals.
