Cisco ups investment in PHY supplier

Company participates in Aquantia's 8th funding round

Cisco Systems has made another investment in a chip supplier it’s been funding since 2005.

Cisco Investments contributed to Aquantia’s $37 million Series H funding, joining new investors Credit Suisse’s Direct Equity Partners, Global Foundries, and Walden Riverwood. Aquantia, which employs 160 people, has raised a total of $199 million since its first round of funding in 2005.

Cisco has participated in each round, Aquantia says.

Aquantia make PHY chips for copper-based 10GBASE-T and multigigabit 2.5G/5G Ethernet networks for enterprise, data center and mobile applications. Cisco is the leading vendor in these markets, and in Ethernet networking overall.

PHY chips are the physical layer circuitry in networking equipment. It connects the Ethernet device to a physical medium like a copper cable or fiber optics.

Intel has also been a strategic investor in Aquantia.
