What is MIPI #1 Specification?

I got several inquiries about adoption rate of physical layers across the mobile and adjacent industries after posting the video showing D-PHY v1.2 silicon on 16nm I realize that it’s debatable if it’s fair to compare one spec vs the other. However, I would like to note that de-facto standard has a lot of weight and it is what sets it apart compared to other potential specifications which only a few vendors select. Once a certain standard is well adopted across the industry, it establishes an entrenched position and cannot be replaced instantly. Any potential replacement standard need to take into consideration backwards compatibility to ensure vendor’s investment in the de-facto standard continues to bear fruits. It requires a phased approach towards replacing a successful standard and it’ll only be possible if the replacement standard has proven benefits compared to the de-facto standard and that the transition period is not long and not painful.

Demand your M-PHY

MIPI Alliance’s M-PHY specification v3.0 provides a solid specification targeted to a variety of applications in the mobile electronics space. I hear some concerns about that this technology is new and engineers prefer to wait for the adoption to pick up before they use it.

Demonstrating M-PHY v3.0 Silicon

MIPI M-PHY is a promising technology, intended to be used across multiple applications and utilized by standard organizations such as JEDEC for UFS, USB for SSIC, and PCI-SIG for Mobile PCIe. We have been working in the past several months to develop and prove M-PHY in HS-Gear3 operation as the specification evolves in the MIPI PHY Work group. Our deep involvement in the group allowed us to develop the M-PHY which is fully compliant to the latest M-PHY v3.0 specification. In March 2013 during the MIPI Face-to-face meeting we demonstrated M-PHY operation in HS-Gear3 and showed it to everyone on the floor. I received a lot of requests to share the video of this demo and now it is ready.

Meeting power, performance and reusability requirements for mobile systems

Discussing and sharing opinions is what drives our industry forward; however sharing ideas becomes more challenging in our time where competition is intense. This is true for any industry but even more relevant to the high-pace mobile market where wrong move can cost you a fortune. It is that important then to stay connected and aligned with market trends so you’re not caught off guard and mitigate design and market risks while enabling to take a leadership position.

Shifting to High Speed Gear 3

The MIPI alliance announced the release of M-PHY v3.0 in Barcelona which solidifies the Gear3 and other specs enhancements. From the press release I can quote this:M-PHY® v3.0 delivers a low-power, scalable physical layer with a data rate range nearing 6Gbps. CSI-3 has been adopted and is available for MIPI Alliance members. LLI v2.0 and M-PHY® v3.0 are scheduled for adoption by the end of April 2013.

Design for Phablets

I spent last week at Mobile World Congress 2013 in Barcelona, where Synopsys also demonstrated our D-PHY, CSI-2 and DSI protocols running in hardware and connecting to Agilent test equipment and UNH conformance test suite.

DigRFv4 System Demo

Mobile devices that use baseband processors and RFIC’s require a lot of effort to integrate these componenets together in a very challenging environment: small and slim board, tight casing, lots of RF components that may cause noise. Adding to that integrating new interface between the baseband processor and RFIC makes this integration work even more difficult. Synopsys can assist and reduce the integration risk and interface adoption easy for those who selects to integrate this kind of interface, namely the DigRFv4. Here’s a short video that demonstrates our integration effort with hardware prototyping system that emulates the baseband processor DigRFv4 interface and connects to Fujitsu RFIC hardware system.

Making the case for LLI

I wanted to make a few points about why you should think of implementing LLI (and M-PHY) in your next design. But first, I want to invite you to a live webinar conducted by Synopsys and Arteris that will explain the implementation and best practices when implementing LLI.
