Integrated Device Technology has agreed to purchase the SigmaTel AC-97 and High Definition Audio (HD-Audio) PC and notebook audio codec product lines.

Based on the terms of the transaction, IDT will acquire both the product lines and related software for $72m in cash.

In addition, IDT will acquire the SigmaTel intellectual property and employee teams, running them as an independent business unit primarily located in Austin, Texas.

“We believe the PC audio market is undergoing an important evolution with expanding media usage models as part of Microsoft’s Vista operating system, Intel’s Viiv platform and the growing importance of voice-over-IP," said Greg Lang, IDT's president and CEO.

"These new platforms will drive the ongoing need for improved audio quality and capabilities."

The firm said it will continue to develop products based around SigmaTel's roadmap.

The transaction, which has already received regulatory and related approvals, is anticipated to close by the end of July.
