Mipi D Phy 20 Specification Top < PROVEN ● >
Alex’s team needs to interface a new 20MP, 4K@60fps camera sensor (CSI-2) with an application processor. The sensor uses MIPI D-PHY v2.0 . The old v1.2 PHY can’t handle the bandwidth. Alex pulls up the MIPI D-PHY v2.0 Specification Top-Level document.

v2.0 introduces bidirectional data lanes (optional) – you can reuse a data lane as a half-duplex reverse channel, saving pins. Alex’s team needs to interface a new 20MP,
For a pass at v2.0 compliance, the eye height must be > 80mV and eye width > 0.35 UI (Unit Interval). At 4.5 Gbps, one UI is roughly 222 picoseconds. This is an extremely tight mask, requiring low-loss PCB materials (Megtron 6 or better) for long traces. Alex pulls up the MIPI D-PHY v2
