Versions 1.4 and beyond of UniPro support both the D-PHY as well as M-PHY<ref>[https://members.mipi.org/mipi-adopters/file-fix/Specifications/VotingBoard%20Draft20Approved/mipi_M-PHY_specification_v0PHY_specification_v1-9000-00_r0-0500.pdf MIPI Draft Specification for M-PHY version 01.9000.00 r0.05], requires an account at the MIPI website</ref> technology. The M-PHY technology is still in draft status, but supports high-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]]. Again, a PHY capable of transmitting user data at 1000 Mbit/s is typically specified as being in 1250 Mbit/s mode due to the 8b10b encoding.
