The specification, released in March 2016, represents a significant leap in data throughput and physical layer efficiency for mobile and automotive applications. It serves as the high-speed serial interface backbone for camera (CSI-2) and display (DSI-2) protocols, balancing the intensive bandwidth requirements of high-resolution imaging with the strict power constraints of portable devices.

Achieving the promised 4.5 Gbps requires more than a spec-compliant chip. The -down design must extend to the board level. The specification, released in March 2016, represents a

This is the thoroughbred. The spec defines a source-synchronous, differential, low-swing signaling interface. By keeping the swing low (typically 200mV) and the termination switchable, it achieves the bandwidth required for 4K video streaming or high-megapixel burst photography without melting the battery. The transition times defined in the spec are aggressive, pushing the limits of what standard PCB traces can handle without becoming transmission lines.
The PPI is the bridge between the PHY and the protocol controller (CSI-2 or DSI-2). The "top" specification for v2.0 defines a faster PPI clock to handle the 4.5 Gbps throughput without back-pressure.
