About Silicon Line


Silicon Line is a leading global provider of innovative ultra-low power optical link technology which enables thin, light and long high speed cables for mobile and consumer electronics markets.

Founded in 2005 as an analog IC design house, Silicon Line quickly developed proven expertise in ultra-low power, analog and mixed-signal design. One of the ICs Silicon Line developed during this period has since gone on to sell over 1.4 billion pieces.

Building on these competencies, Silicon Line next started to develop our own products with the vision to provide the most power efficient and best in class analog signal ICs for optical data transport in mobile devices and consumer electronics applications. Silicon Line now has a wide portfolio of physical layer ICs plus associated SerDes ICs for multi-gigabit optical links and holds multiple patents associated with these products.

Today’s consumers have an ever expanding expectation of higher resolution images and video as well as high speed data transfer to storage devices. Slim 4K TVs are now common, 4K notebooks , tablets, smartphones and cameras are also all available. Storage of 4K content on external hard disks is also required. 8K products are coming soon. In addition VR / AR (Virtual / Augmented Reality) products which require high resolution and high speed data transfer are becoming mainstream.

This has led to the development of several high speed cable standards such as DisplayPort, HDMI and USB 3.1 as well as new very slim connectors like USB Type-C which are needed for the latest slim form factor designs. However, conventional copper cables for these standards are thick, bulky, heavy and limited in length to 1m or so depending on the data rate. Copper has reached its limit.

Low cost, low power, long, thin and light active optical cables are therefore replacing copper cables in these high speed applications. Silicon Line is playing a key role in this process by making available both ICs and modules which allow quick and easy high volume manufacture of these new active optical cables.

The same data rate explosion has also occurred inside devices such as tablets, notebooks and TVs where high speed connections using standards such as MIPI D-PHY, eDP and VbyOne are needed between the application processor and the internal displays / cameras. In addition these devices have very demanding requirements for low power consumption, very small form factors and also EMI reduction. Optical connections are ideal for these applications and Silicon Line enables this by providing IC solutions to this market.

Silicon Line leads the way in consumer optical technology and has been first to the market with several products:

  • First to offer an optical MIPI D-PHY interface (CSI-2, DSI) for notebooks / tablets / TVs
  • First to offer optical HDMI (18 Gbps)
  • First to offer optical USB 3.1 (10 Gbps)
  • First to have an optical embedded DisplayPort interface for notebooks

Silicon Line products are also widely used in industrial, medical and security applications.

Silicon Line is a privately held company. Our headquarters are in Munich, Germany and we have offices in Korea, Japan, Taiwan, China as well as the US.
