CS48540-CQZ General Description

The 32-bit CS48520 and CS48540 audio DSPs are designed to enable unique digital signal processing audio software features for flat-panel digital television applications. The CS48520 and CS48540 ICs give OEMs a cost-effective and simple-to-design solution capable of providing an extensive selection of audio features that allow OEMs to provide consumers with enhanced audio features and maximize the flat-panel television’s overall audio system. The CS48520 provides four channels of in/out audio and is ideally designed for two or 2.1-channel stereo applications, whereas the CS48540 provides eight channels of in/out audio and is targeted for multi-channel systems. Among the consumer features that can be implemented using the CS48500 family: Multi-channel and virtual surround sound, Dynamic volume control, Enhanced listening modes, Bass management, Speaker and cabinet tuning, Automatic room equalization, A/V sync delay. To assist manufacturers, Cirrus Logic also provides DSP Composer™, a PC-based graphical interface software tool designed to give engineers a simple, powerful user interface from which to configure the audio processing performed by the ICs. Support for home audio applications is through a third party. Please contact your local sales representative for information.
