Company profile
researched Aug 2026Aeluros, Inc. was a fabless semiconductor company that designed serial, high-performance, high-density physical layer (PHY) solutions in mainstream CMOS technology for wireline communications operating at 10 Gigabits per second. Its products were physical-layer integrated circuits used in 10 Gigabit Ethernet line cards and optical modules, including XENPAK, SFP and XFP form factors, along with Ethernet transceivers and transmission devices sold to semiconductor, networking OEM and optical module customers worldwide.
The company combined merchant silicon with a licensing and consulting business built around intellectual property cores addressing SATA, PCI Express and XAUI physical-layer requirements at data rates of 2.5 to 3.125 Gbps, which were adopted by semiconductor suppliers seeking higher integration. Later development work focused on PHYs with integrated electronic dispersion compensation for 10GBASE-LRM applications using SFP+ transceivers. Aeluros was headquartered in Mountain View, California and had approximately 50 employees.
Founding story
Aeluros was founded in June 2001 to develop 10 Gigabit Ethernet interface technology, and by the time of its acquisition was led by CEO Stefanos Sidiropoulos with a team of analog engineers focused on highly integrated 10 Gbps systems.
Business model
Aeluros designed and sold analog-intensive integrated circuits to optical module manufacturers and system integrators as a fabless semiconductor company, and supplemented product sales with a licensing and consulting business around IP cores for computing, communications and storage applications.
Sales of physical-layer integrated circuits for 10 Gigabit Ethernet and 10 Gigabit Fibre Channel applications, together with revenue from licensing IP cores and consulting services.
Traction
Brought to market a family of silicon products for the 10 Gbps datacom and storage markets, released three IP cores for computing, communications and storage, and secured design-ins at leading networking OEMs and optical module manufacturers ahead of its 2007 acquisition.
Latest developments
The acquisition by NetLogic Microsystems was announced in October 2007 and expected to close within about ten days; NetLogic was later acquired by Broadcom in a transaction that closed in February 2012.
▸Full profile — market position, technology, go-to-market, geography, history
Market position
Aeluros was positioned as a supplier of low-power 10-Gigabit interface technology in mainstream CMOS processes, an area NetLogic described as a scarce engineering capability that would form its center of excellence for high-speed interface technology. Its products were designed into next-generation systems at networking OEMs and optical module manufacturers.
Emphasis on low power, low cost and high density achieved by implementing 10 Gbps physical-layer functions in mainstream CMOS, including breaking the 1 watt barrier for XAUI transceivers and integrating electronic dispersion compensation on-chip.
Technology
Aeluros developed mixed-signal CMOS physical-layer devices for 10 Gbps communications. Reported industry firsts include a XAUI transceiver dissipating less than 1 watt, a transceiver able to drive a 10 Gbit/s VCSEL directly, and a transceiver with integrated electronic dispersion compensation for 10 Gigabit Ethernet over multi-mode optical fiber. The company also released IP cores for SATA, PCI Express and XAUI physical layers at 2.5 to 3.125 Gbps. Technical results were published at the IEEE International Solid-State Circuits Conference, including an 800 mW 10-Gigabit Ethernet transceiver in 0.13 um CMOS.
Go-to-market
Direct engagement with optical module makers, networking OEMs and system integrators for design-ins, complemented by IP core licensing to semiconductor suppliers; Series B capital was raised partly to support Pacific Rim and Asian market focus in Ethernet and storage.
Optical module manufacturers, networking original equipment manufacturers, system integrators, and semiconductor suppliers licensing physical-layer IP cores.
Geography
Headquartered in Mountain View, California, serving customers worldwide, with stated commercial focus on the Asian and Pacific Rim markets for Ethernet and storage.
History
Founded in June 2001, Aeluros raised a $10 million Series B round in October 2004 led by UOB Venture Management with participation from existing Series A investors New Enterprise Associates and Worldview Technology Partners. It shipped a family of 10 Gbps datacom and storage silicon products and IP cores, and in October 2007 signed a definitive agreement to be acquired by NetLogic Microsystems for $57 million in cash plus up to $20 million in milestone payments. NetLogic itself was acquired by Broadcom Corporation for $3.7 billion, with the transaction closing in February 2012.
