Dual displays require two DSI interfaces. v2.5’s low-power state efficiency ensures that pushing video to the cover display while the main display is off doesn’t drain the battery.
Even with the PDF, engineers make mistakes. Here are the top three traps: mipi d-phy specification v2.5 pdf
The headline feature of v2.5 is the extension of the maximum HS data rate. While v2.0 topped out at 2.5 Gbps per lane, v2.5 pushes the envelope to 4.5 Gbps per lane. For a 4-lane configuration, this yields a theoretical aggregate bandwidth of 18 Gbps—essential for 8K video, high-frame-rate sensors, and AR/VR displays. Dual displays require two DSI interfaces
In HS mode, the v2.5 spec mandates precise differential impedance matching. The specification calls for a differential impedance of 100 Ohms (differential) and a common-mode voltage ($V_CM$) that is tightly regulated to ensure signal integrity at 4.5 Gbps.
