: This feature optimizes the speed at which a link switches between high-speed serial communication in one direction and control communication in the reverse direction. It significantly reduces upload and download latency, which is critical for real-time sensor feedback.
Up to 4.5 Gbps per lane (Standard Channel); up to 6 Gbps (Short Channel).
24 Gbps aggregate throughput (using a 4-lane configuration). mipi d-phy specification v2.5 pdf
: One of the most impactful additions, ALP replaces legacy Low Power (LP) signaling with pure, low-voltage differential signaling. This allows link operation over longer channels (up to 4 meters) and aligns with the industry trend toward lower voltage levels in advanced semiconductor processes.
Point-to-point differential with modular data and clock lanes. Supports interconnect lengths up to 4 meters. Compliance Backward compatible with v2.1, v1.2, and v1.1. Major Innovations in Version 2.5 : This feature optimizes the speed at which
Compared to , which supported speeds up to 4.5 Gbps, v2.5 focuses on efficiency and versatility rather than raw speed increases. It provides the necessary infrastructure (ALP/BTA) for the CSI-2 and DSI-2 protocols to operate more efficiently over longer distances without requiring a move to the more complex MIPI C-PHY or M-PHY . A Look at MIPI's Two New PHY Versions - MIPI.org
: Used in ADAS sensors, radars, and high-resolution dashboard displays where low EMI and high reliability are paramount. 24 Gbps aggregate throughput (using a 4-lane configuration)
: Introduced HS-TX half swing mode and HS-IDLE mode , which provide designers more flexibility to minimize power consumption during data transmission bursts. Primary Applications
: By combining Fast BTA and ALP, version 2.5 enables the USL feature found in MIPI CSI-2 v3.0 . This allows a single high-speed link to handle both pixel data and sideband control commands, effectively eliminating the need for separate I2C/CCI wires and reducing overall pin count.
