CM6535 USB Audio Chip DESCRIPTION The CM6535 is a USB 2.0 audio chip builds in 8051 for flexible applications with Tri-Colors PWM LED driver, two (2)-channel ADC/DAC and S/PDIF and I2S interface makes it suitable for headset, notebook/ mobile docking, speaker and microphone applications. The internal 8051 can also be developed to different applications, such as Microsoft™ Lync/ Skype/VoIP device and Android Phone or Tablet/Slate docking device. The CM6535 is compatible with USB Audio Class 1.0 and USB 2.0 full-speed, thus it can plug and play without additional software installation on the major operation systems. The internal DAC/ADC and I2S support 8~96 KHz sampling rate and 16/24bits resolution.
