Cirrus Logic Inc is to create a separate company to handle its PC modem business. Ambient Technologies Inc will acquire Cirrus' PC modem products and become a licensee of its patents. The modem business, which employs about 40 people, only accounts for about 6 per cent of Cirrus' consolidated revenue. Sold under its own name and the Crystal brand, Cirrus supplies products to the mass storage, communications, consumer electronics and industrial markets. ®
