Overview
General Info
-
Overview
MIPI DigRFSM is a high-speed interface that is used to interconnect the RFIC in a device with the baseband processor. It is designed to provide a convenient approach for integrating components and meeting the data-intensive needs of 4G LTE air interfaces that require high channel bandwidth.
-
Implementation
It is a low-complexity solution for complex implementations that typically require multi-mode, multi-band operation. It natively handles MIMO configurations, receive diversity and carrier aggregation. In addition to LTE, it supports HSPA+, 3.5G and 2.5G air interfaces.
-
Performance Highlights
MIPI DigRF is a high-level interface that operates on the MIPI M-PHY physical layer, enabling a single link between the baseband and RFIC. MIPI DigRF focuses on the protocol and programming used to interface the components, enabling vendors to differentiate their overlying system designs while providing interoperability at the interface level between compliant ICs.
The interface is flexible and scalable, allowing use of multiple receivers and transmitters simultaneously. At the same time, it helps minimize pin count and overall interface power consumption, and manages electromagnetic interference (EMI).
