CM6400-EVB is an evaluation board for the CM6400.
   
About CM6400:
    
CM6400 is an advanced highly-integrated USB audio single chip optimized for featured USB headset or other audio applications. CM6400 integrates 5-band hardware digital equalizer (EQ) processing unit with up-to-4 presets to fit different applications or improve headphone SPL characteristics. In addition, embedded Mic Auto-Gain-Control (AGC) and clipping-protection functionality could automatically adjust variant sound input scale to get rid of large signal clipping and also get more constant recording level during voice communication. With outstanding SNR/THD audio performance overtaking WHQL standard and its versatile HW functions, CM6400 is the ideal all-in-one USB headset chip that could empower and differentiate your product ideas at your own will.
    
CM6400 Advantages:
  • Integrates 5-Band Hardware Equalizer with up-to-4 preset modes , configurable gain value of each band could be customized by EEPROM parameters
  • Built-in Automatic Gain Control (AGC) and clipping protection for microphone recording (Enabled by EEPROM)
  • Mic-In signal clipping-detection LED indicator
  • Multimedia “Play/Pause, Stop, Next, Previous” HID hot-key controls
  • Supports serial 24C02 EEPROM programming interface for customizing VID/PID/Product String / Manufacture String / Serial Number / Volume Range / Initial Volume / HID_Disable / EQ /AGC and other configuration
  • Windows® VISTA Premium / Windows® 7 Logo Program compatible
