Arasan, a provider of IP for semiconductor design and manufacturing, has revealed that it is now supporting MIPI CSI-2 v1.3 with extended lane support and the industry's first combination C-PHY + D-PHY physical interface. According to the company, the Total CSI v1.3 IP solution comprised of both transmitter and receiver digital controllers, and the C-PHY-D-PHY combination analogue interface, promises to offer advanced sensor performance, e.g. UHD (3840 x 2160) at 60fps, WQHD (2560 x 1440) at 120fps and HD (1920 x 1080) at 240fps.

4K cameras are expanding as sub-$500 models have been introduced for Sports Action. Drones, IP surveillance and prosumer markets will drive expansion of features and performance.

"Our combination C-PHY/D-PHY physical interface gives application processor developers flexibility to support evolving MIPI standards for camera sensor and display interface," said Prakash Kamath, CTO at Arasan.

CPHY achieves high bandwidth through a unique encoding where 16 bits of input data is encoded into seven symbols and each symbol is transmitted over a 3-phase encoded line. CPHY reuses the similar low-power signalling as the DPHY. CPHY is designed such a way that it can co-exist sharing the same lines as DPHY.

Arasan's CPHY/DPHY combination universal PHY which can be configured both as transmitter and receiver. Arasan's novel and innovative design techniques allowed sharing a number of modules between the CPHY and DPHY with no impact on performance resulting in optimal area and power. It can work with both old DPHY systems and new C-PHY systems. Arasan has been a contributing member of MIPI for over ten years with a long history of customer engagements in MIPI camera and imaging. Arasan works closes with the MIPI Camera working group that includes leading camera sensor suppliers as well as application processor developers.

The Total MIPI CSI v1.3 IP solution includes CSI-2 v1.3 transmitter and receiver controllers and the C-PHY/D-PHY combination physical interface. The Total CSI v1.2 IP solution for D-PHY is also available. Arasan's D-PHY has been ported to a range of foundries and process nodes from 180nm to 28nm.
