v2.5 includes optimizations in the turnaround state (TAT) and Bus Turnaround (BTA) procedures. This reduces the overhead time required to switch the direction of data transmission (e.g., switching from the display sending touch data back to the processor), improving overall system responsiveness.
The most significant change in v2.5 is the increase in maximum data rate.
You might wonder: Why not just use MIPI C-PHY or D-PHY v3.0?
The v2.5 specification is primarily targeted at:
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.
