CS48L10/11 Overview
The CS48L10 ultra low power voice and audio DSP chip has been designed to bring best-in-class audio processing capability to mobile/portable applications, while having minimum impact on overall system power consumption. The CS48L10 provides designers with the opportunity to enhance, improve, and differentiate their products, while simultaneously reducing the audio-processing burden from the main system processor. Support for home audio applications is through a third party. Please contact your local sales representative for information.
