MIPI M-PHY is a physical layer that provides high-speed data transfer with much low power consumption as compared to other PHY options. Because of its low power operation and speed flexibility it is widely accepted for implementing interfaces on mobile devices.
Initially MIPI introduced M-PHY version 1.0 in 2011 which supports a maximum transfer rate of 1.45 Gbps in HS-GEAR1. Later in 2012 MIPI releases M-PHY version 2.0 with support of HS-GEAR2 (maximum transfer rate of 2.9 Gbps). In 2013 MIPI announced M-PHY version 3.0 having full support for HS-GEAR3 (maximum transfer rate of 5.8 Gbps). Recently spec for MPHY 3.1 was also released.
In this blog, we will summarize the technical differences between M-PHY 3.0 and M-PHY 2.0 specification:
