Described as an "industry leader" by the semiconductors brand, Mr Scarisbrick also serves as executive chairman of Cranberry Township-based Netronome Systems, a network flow processor developer.
He also serves on two other company boards: Innovative Silicon, based in Lausanne, Switzerland and ARM Holdings of Cambridge, England.
The latter is the world leader in intellectual property for the microprocessor market, Inphi says.
As a member of Inphi's Technical Advisory Panel, Mr Scarisbrick will collaborate on the provision of strategic insight on technology and company direction.
The news follows Inphi's announcement that it has opened a design centre based in the UK to research high-speed analogue semiconductor solutions.
Interface devices which are intended for use with 100 Gbps networks are a particular area of focus for the centre, which is located in Preston Deanery in Northamptonshire.
