The Arasan DSI v1.3 Receiver Controller IP is designed to provide MIPI DSI 1.3 compliant high-speed serial connectivity for device (mobile display modules) with Type 1 to 4 architectures. Serial connectivity to the mobile applications processor’s DSI host is implemented using 1 to 4 D-PHY’s (also available from Arasan), depending on display bandwidth needs. This IP connects to the D-PHYs through the PPI interface.
Display modules consist of display driver logic driving display signals onto a display device or panel. On the display driver side, Arasan’s MIPI DSI Device Controller provides the DBI Interface for Types 1 to 3 display modules and the DPI Interface for Types 2 to 4 displays.
Initial configuration of this DSI Device Controller IP can be done through programmed IO over the AHB bus, however, other bus interfaces can be provided upon request.
