Cirrus Logic’s Enhanced PC Audio Controller Delivers Superior PCI Performance
Following the success of its popular CS4280 PCI audio solution, Cirrus Logic Inc. has introduced a higher-performing, lower cost PCI audio controller, the CS4281.
In addition to addressing the basic audio requirements of PC designs and providing support for industry standards and legacy applications, the CS4281 also supports multiple sample rates with internal sample rate converters.
The new chip, pin-compatible with a variety of Crystal(TM) audio solutions, provides a high-quality PCI audio at an affordable ISA price point. With the addition of the CS4281, the Crystal audio family offers PC manufacturers a broader choice for increasing the economy, reliability, and convenience in their PC audio subsystems.
With its support for sample rates from 8 to 48kHz, the CS4281 supports all multimedia file types, and increases system design flexibility. Further, this device can handle multiple streams of data for systems that include a software modem and/or multiple audio channels, thereby supporting streaming audio in gaming and Internet applications, and true audio surround sound using up to eight speakers.
