概述

Quartet was introduced in 1998 and started shipping in early fiscal 1999. Quartet builds on the Duo series by addressing the needs of device manufacturers serving the consumer mixed-signal, or CMS, marketplace. CMS devices combine the power of digital processors with CD quality audio, broadcast video and wireless communications onto a single, cost-sensitive SoC. The Quartet, the first of the Quartet series, addresses all four of these requirements in an integrated, ready for volume production package. With 200 MHz digital, 20 bit audio and 300 MHz video, Quartet is designed to meet the demands of the most complex SoC devices. In fiscal 2004, as part of the integration of the NPTest business, we communicated to customers that future SoC research and development would be focused on the Sapphire platform.
