Due to the higher demand for better displays, bridging applications has become increasingly popular. One very common application interface is the Mobile Industry Processor Interface (MIPI®) D-PHY. It was developed primarily to support camera and display interconnections in mobile devices, and it has become the industry’s primary high-speed PHY solution for these applications in smartphones today. It is typically used in conjunction with MIPI Camera Serial Interface-2 (CSI-2) and MIPI Display Interface (DSI) protocol specifications. It meets the demanding requirements of low-power, low noise generation, and high noise immunity that mobile phone designs demand.
MIPI D-PHY is a practical PHY for typical camera and display applications. It is designed to replace traditional parallel bus based on LVCMOS or LVDS. However, many processors and displays/cameras still use an RGB or CMOS as interface. Hence, in order to connect to a MIPI D-PHY IP, a converter logic is required to convert the parallel interface into MIPI D-PHY byte packet compatible format.
