| Parameter | MIPI D-PHY v1.2 | MIPI D-PHY v2.0 | |-----------|----------------|-----------------| | Max data rate per lane | 2.5 Gbps | 4.5 Gbps (6 Gbps optional) | | HS differential swing VOD | 200 mV typical | 140–300 mV (wider range for signal integrity) | | LP voltage | 1.2V or 1.8V | 1.2V or 1.8V (unchanged) | | Common mode voltage | 200 mV | 200 mV (but with tighter tolerance) | | UI jitter (RMS) | <0.3 UI | <0.15 UI | | Max channel insertion loss | ~6 dB @ 1.25 GHz | ~12 dB @ 2.25 GHz (with equalization) |

v2.0 preserves these modes but tightens the transition timings. For instance, the entry procedure (LP to HS) is optimized, reducing the time overhead from microseconds to nanoseconds. This matters for bursty sensor readouts where frequent mode switching is required. mipi d phy 20 specification top

: Maintains the core D-PHY characteristic of switching between High-Speed (HS) differential signaling for data transfer and Low-Power (LP) single-ended signaling for control and power management. | Parameter | MIPI D-PHY v1

: Used for control signals and state transitions to significantly reduce battery drain during idle periods. Ideal Use Cases : Maintains the core D-PHY characteristic of switching
