T_clk-post (clock post-settle) = 60 ns + 4 x UI (Unit Interval). Fixed Text (Errata): T_clk-post = 60 ns + 4 x UI, but must also be ≤ 120 ns for data rates > 3 Gbps.

The v2.5 update maintains high performance while introducing specific power-saving and calibration features: Standard Channel: Up to 4.5 Gbps per lane. mipi dphy specification v25 pdf fixed
Switches to single-ended signaling (CMOS levels, typically 1.2V) for control and management tasks, consuming minimal power. Universal Lane:
The MIPI D-PHY specification v2.5 PDF introduces several new features and enhancements over its predecessor, including: T_clk-post (clock post-settle) = 60 ns + 4
Ensuring the interactive PDF accurately links to corresponding appendices and protocol layers (e.g., matching D-PHY parameters to CSI-2 v2.1/v3.0 requirements).
The MIPI D-PHY v2.5 specification builds on the v2.1 baseline, primarily focusing on distance and power efficiency. The official full MIPI D-PHY specification is reserved for MIPI Alliance members, but the following guide outlines the critical architectural and electrical updates introduced in this version. 1. Key Performance Specifications The v2
MIPI D-PHY v2.5 maintains the robust high-speed (HS) capabilities of its predecessors while optimizing for shorter and longer channels:
Enhanced preamble sequences ensure improved synchronization at higher throughputs. Power Saving and Signal Integrity
MIPI, like IEEE or JEDEC, releases Errata documents after the initial publication. If v2.5 had a typo in a timing equation (e.g., T_hs-prepare vs. T_hs-prepare + skew ), the Errata would correct it. Engineers call a PDF that has these corrections merged into the main text a "fixed" version. However, MIPI rarely merges errata into a new "v2.5-rev1". Instead, you download the base spec plus the Errata PDF.
