Chip maker Provigent received $10 million in fifth-round funding, all from Lightspeed Venture Partners, to develop chips for 4G cellular base stations and wireless applications. The funds will also be used to extend sales efforts globally — the Santa Clara, Calif.-based company is already active in Europe and Asia.

Provigent has raised $51 million to date from the likes of Ascend Technology Ventures, Delta Ventures, Globespan Capital Partners, Magma Venture Partners, Pitango Venture Capital, Sequoia Capital, Stata Venture Partners and Viterbi Group. It last raised capital in March, taking $3 million from Stata to cap off a fourth round worth $20 million.
