BusinessWire: MIPI Alliance updates its MIPI M-PHY specification to v4.0, and adds a fourth gear (Gear 4 at 11.6 Gbps), to double the potential bandwidth per lane compared to the previous specification. It introduces adaptive receiver equalization to improve support for challenging channels while maintaining the peak transmission rate of 11.6 Gbps/lane or 46.4 Gbps over 4 lanes. It also scales optical media converter (OMC) data rates up to Gear 4, to build connections that are meters in length to support MIPI M-PHY’s use on more types of devices and the growing market for mobile-influenced platforms, such as automotive systems.
Support for M-PHY v4.0 will be included in the next versions of MIPI UniPro and MIPI CSI-3, which will undergo development later in 2015. Cameras that use CSI-3, when based on UniPro enabled by M-PHY v4.0, will be able to transmit 4K video with 60 fps and 12 bits per pixel on a single differential pair.
“We are pleased to announce that MIPI M-PHY will deliver a peak data rate of 11.6 Gbps on one lane and increase bus and system efficiency,” said Joel Huloux, chairman of the board of MIPI Alliance. “The new specification dramatically bolsters performances and throughput of data transmitted on 2 pins and offers companies new opportunities to enhance the capabilities of protocols that operate on this technology.”
“I want to emphasize as well that advancement of M-PHY does not stop with this release,” said Henrik Icking, chair of the MIPI Alliance PHY working group. “The working group plans to continue evolving this versatile specification to meet future data transport needs for mobile and mobile-influenced ecosystems.”
