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, 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.
