The Mobile Industry Processor Interface (MIPI®) Alliance is an organization of leading companies in the mobile industry defining and promoting open interface specifications for mobile terminals in order to address the design challenges of next-generation mobile phones.

The MIPI DigRF interface is a high speed, serial, digital chip to chip interface and communication protocol between Baseband processor ICs and RF IC enabling increased reliability, lower power, lower pin count and increased interoperability.

The v4 specification of the MIPI DigRF interface is based on a scalable architecture providing significantly higher bandwidth than the v3 version and relies on the MIPI M-PHY as a physical layer. It is intended to be used in mobile terminals that support high bandwidth mobile broadband technologies such as LTE and Mobile WiMax.

The DesignWare DigRF v4 Master Controller core implements all the functionalities defined for the protocol layer of the DigRF v4 interface. It is fully configurable to enable support for up to 4 Rx Channels and 4Tx Channels and can be used for basic handset configurations as well as with local and remote diversity.
