The DigRF v4 v1. The RFFE v1. As the global leader in mobile interface technology, MIPI Alliance includes members who are intimately involved in radio technology. Both of these specifications expand on previous versions, addressing the increasingly complex market demands of multi-radio, multi-band wireless architectures. What applications are targeted with these specifications?

Are these specifications backwards-compatible with their previous versions? DigRF v4 v1. If a company has begun implementing previous versions of the specifications, should they transition to the more current version? Or can they continue their development work? RFFE: Development can continue with v1. Provided that the requirements as stated in v1. When were the first versions of these specifications released? RFFE v1. DigRF v4 1. Visit www. Who can use these MIPI specifications?

Are there other organizations that develop interface specifications for the radio portion of wireless devices? Yes, MIPI Alliance believes that radio systems and air interface technology will continue to grow in complexity.

If both of these specifications target the radio, why are there two separate working groups? While both address the radio portion of a wireless device, each group focuses on a unique portion of the radio. What does DigRF v4 v1. What is different between v1. It was created as a means to update information about, and references to, the v1.

At the same time, extensive updates to the DigRF v4 specification were undertaken to clarify details of the DigRF v4 interface. No significant technical changes to DigRF v4 exist between v1. What are the key attributes of the specification? What are the key benefits for this specification? DigRF v4 provides a standardized interface. This high-speed serial interface technology provides optimized power efficiency via multiple speed modes and fast cycling between active and power-saving operations.

It does so while also providing for low EMI operational impact, as well as protection from interference induced into the interface Q. Does this specification include a physical layer?

What is not included in the specification? However, some system aspects - such as EMI - are included to enable optimal performance and operations. Which companies developed this v1. Arasan Chip Systems Inc. Other companies have provided support and suggestions.

Is there a roadmap for this specification? What is unique to DigRF v4 compared to other high speed interfaces? This specification offers the ability to manage and minimize EMI issues in a radio frequency environment. DigRF v4 provides a protocol and a set of operating modes tailored to the needs of a BB to RFIC interface and allows control messages with very low latency. This offers flexibility and scalability for air interface standards. Is DigRF v4 already used in products that are on the market?

Yes, multiple vendors offer solutions incorporating DigRF v4. What does RFFE v1. The specification defines a control interface for RF Front-End devices including, but not limited to, power amplifiers, low-noise amplifiers, filters, switches, power management modules, antenna tuners and sensors. The interface is a compact two signal serial interface clock and data designed for low gate count, low current consumption and low EMI.

The Application Note discusses and explains informative or more implementation-related issues. The PICS document is the Protocol Implementation Conformance Statement which may be used by a device implementer to identify the capabilities and options of the protocol that have been implemented, or by a systems designer to verify device capabilities.

As per MIPI specification numbering policy, a change to the minor number revision field indicates that only relatively minor changes have been made to the document. While a better understanding of certain requirements or parameters could result in alternate implementation decisions by a user, it was not the intention of this release to require any changes to existing device designs.

RFFE is a common interface which allows interoperability for many different devices in a RF front-end. Analog signal paths required between the front-end devices and other elements that control and utilize devices are outside the scope of the RFFE specification.

Analog Devices Inc. The WG is actively developing requirements and technical details for a next generation update to the RFFE specification. The time frame for this is not yet determined.

MIPI DigRF

Connecting radio frequency transceivers in mobile devices to baseband modem EMI-sensitive high data rate applications Highly reliable links with error protection Real-time interfaces with low latency and fast start-up time Interfaces with packet-oriented traffic bursts Transferring sample data with adjustable word length Combined control and data traffic with flexible protocol adjustment Industries 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. 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. 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.
