This report provides a general overview of the MIPI D-PHY Specification v2.5 and is not intended to replace or supersede the official specification. For detailed information, please refer to the official MIPI D-PHY Specification v2.5 document.
Reduces power consumption during high-speed data transmission by using a smaller voltage swing.
MIPI D-PHY v2.5 maintains the robust high-speed (HS) capabilities of its predecessors while optimizing for shorter and longer channels:
Earlier revisions left room for interpretation during the High-Speed Entry ( LP-11 →right arrow LP-01 →right arrow
