Usb 2ch Audio Controller For Speaker

  CM102-A+ /102S+ series is a highly integrated single chip for USB stereo Speakers application. Minimum external components are needed for building an USB Speaker system, which makes CM102-A+ /102S+ a simple and very cost-effective solution. Since no driver is necessary for Audio playback on all major OS. CM102-A+ /102S+ provides a truly plug-and-play feature for external digital Audio playback. For energy saving, USB suspend mode and resume is supported by CM102-A+ /102S+. With Power Amplifier enable pin and volume control VR input pin, a traditional Speaker front panel design can be built. This new single chip not only support 44.1KHz and 48KHz sampling rate playback but also with X2 modulation for hi-frequency quality. Better yet, simplify anti-pop noise solution was embedded on chip for general 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 ADC DAC component but also integrated digital control Power Amplifier function for USB digital sound application. The Dynamic Range Control function can support high efficiency volume output to get loudness sound effect similar D class amplifier capability. Vender can just using single chip to saving external amplifier component and getting a better listen experience when listen to a music source with wide dynamic range. Moreover, customers can use C-Media USB Audio Driver with Xear 3D functions to show up digital Speaker features and upgrade PC multi-media stereo function to be a CE like devices. Xear 3D can support 10 band Equalizer, EnvironmentFX sound effects and virtual 7.1CH Speaker shifter. This driver is optional for free bundle.CM102-A+'s datasheet is the same as CM102-A+
