High-speed low-power Serial Link
The future mobile serial link standard has been defined by the Mobile Industry Processor Interface alliance, and is defined as a multi-Gb/s low power differential link. There are two popular standards for the physical layers for these standards: D-PHY and M-PHY. The D-PHY is a mixed-signal core that can be used for both DSI-1 (Display Serial Interface) and CSI-2 (Camera Serial Interface), while different digital controllers are necessary for each of these standards. DSI and CSI are the most popular MIPI-based standards today. Next-generation devices are expected to witness large amounts of data being transferred across the chip-to-chip and chip-to-peripheral interfaces and the MIPI alliance is specifying these interface through a set of new high-speed standards: DigRFv4 (data interface between the RFIC and the BBIC), CSI-3 (data interface between the camera and the application processor), DSI-2 (data interface between the display and the application processor) and UniPro (Unified Protocol that will form the basis for CSI-3, DSI-2 and the Universal Flash Storage (UFS)). All these standards use the MPHY as the physical layer for the interface. The MIPI body is extremely well represented by the industry and has got wide-spread acceptance. It is our firm belief that MIPI will be the standard of the future for mobile chips. Cosmic Circuits is a contributing member of the MIPI Alliance, and will continue to be involved in the specification effort.
Advantages of the MIPI interface
The MIPI interface has been specified to specifically address
Cosmic Circuits DPHY/MPHY
Cosmic Circuits provides silicon proven solutions for both DPHY and MPHY with a roadmap that extends into the advanced deep submicron nodes. These solutions achieve best-in-class area and power and the IP is modular keeping in mind the it’s anticipated wide-spread usage and the need for multiple configurations. Cosmic Circuits offers both universal MPHY cores that can support the entire range of applications and ultra low-area/power DigRFv4 optimized cores specifically targeting the DigRFv4 standard. Reference boards for DPHY and MPHY are available to select customers on request.
The Cosmic D-PHY Advantage
Customization and Support
We are customer-centric in our approach to support. Starting from working hand-in-hand with our customers on detailed specifications, to customizing the IP to specific application requirements, through providing a smooth integration experience (reviews and reviews), all the way through till production ramp. You get to talk directly with our R&D engineers in an easy and direct manner.

"Our mobile application processor SOCs and the market we serve requires differentiation in terms of low-power and low cost. Integrating a MIPI interface reduces system power and allows for easier interoperability. But we needed a mixed-signal partner that could deliver with certainty. Cosmic brought good technology and a supportive team that we could rely on. We are happy that their IP integrated into our chip has worked first pass and being taken to mass production in TSMC. Overall, MTek's experience with Cosmic has been smooth and rewarding"
