CM6120-XL series is a highly integrated single chip for USB Speaker application with 2-Channel Class-D output. Minimum external components are needed for building an USB Speaker system, which makes CM6120-XL a simple and very cost-effective solution. Since no driver is necessary for audio playback on all major OS. CM6120-XL provides a truly plug-and-play feature for external digital audio playback.
    
For energy saving, USB suspend mode and resume is supported by CM6120-XL. This new single chip supports 44.1KHz and 48KHz sampling rate playback, and anti-pop noise circuits are embedded for generic pop noise issues. All of the functions have been approved by USB IF certification program. More flexible and customized design is possible with GPIO pin, which is accessible by USB vendor specific request. This one chip solution not only embedded USB transceiver but also integrated digital control power amplifier function for USB digital sound application.
     
Benefits:
  • Portable and Plug & Play
  • Isolate the Noise Interference from PC / Laptop system
  • Synchronized Digital Volume Control with PC or Laptop
  • Windows® Vista™ / 7 WHQL Certification
  • Single chip Class D output
