CS48520/40

The 32-bit CS48520 and CS48540 audio digital signal processors are designed to enable unique 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 multichannel systems.

Among the consumer features that can be implemented using the CS48500 family:

• Multichannel 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, CS48520/40 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.
