===M-PHY===

Versions 1.4 and beyond of UniPro plan to support both the D-PHY as well as M-PHY technology. The M-PHY technology is still unreleased,only butin isdraft expectedstatus (v0.71), but tosupports supporthigh-speed data rates starting at about 1000 Mbit/s (the M-PHY was named after the Roman number for 1000). In addition to higher speeds, the M-PHY will use fewer signal wires because the clock signal is embedded with the data through the use of industry-standard [[8B/10B encoding|8b10b encoding]].

The D- and M-PHY are expected to co-exist for multiple years because the D-PHY is a less complex technology while the M-PHY provides higher bandwidths despite using fewer signal wires.
