D-PHY is a scalable, low-power, high-speed physical layer. It was originally designed for the mobile industry but has since expanded into automotive infotainment, wearables, and IoT devices. The "D" in D-PHY stands for the Roman numeral 500, reflecting the original target speed of 500 Mbps per lane, though modern versions have far surpassed this limit.
The magic of the D-PHY lies in its ability to switch between two distinct operating modes depending on the situation: D-PHY is a scalable, low-power, high-speed physical layer
Think of it as the translator and the road combined. It takes massive streams of pixel data and converts them into electrical signals that can travel across a PCB or a flex cable from your camera sensor to your phone’s main chip. D-PHY is a scalable
