DSI-2 isn't just a speed bump; it's a significant evolution designed for next-generation displays. Here are its key advanced features:

The MIPI DSI specification is designed to provide a high-bandwidth, low-latency interface for display data transmission. The specification supports a wide range of display resolutions, from small LCD displays to large, high-resolution screens.

To understand the latest physical layers.

is a widely adopted standard proven in the industry for years, offering up to 4.5 Gbit/s per lane with continued evolution. It features a source-synchronous architecture with a dedicated clock lane. Version 3 of D-PHY is expected to be released soon with data rates up to 9 Gbit/s per lane.

The specification defines both a serial bus and a communication protocol. All about MIPI C-PHY and MIPI D-PHY - Arasan Chip Systems
