骅讯 CM6533 内置8051的高品质USB音频芯片

　　Description and Overview

　　The CM6533/CM6533N/CM6533X1/CM6533DHis a USB 2.0 audio chip built-in 8051 for flexible applications. With integrated Tri-Colors PWM LED driver and two (2)-channelADC/DAC and S/PDIFinterface makes it suitable for headset, docking, speaker and microphone applications. The internal 8051 can also be developed to a lot of different applications, such as Microsoft™Lync/Skype/VolP device, Android Phone or Tablet/Slate docking device. The CM6533/CM6533N/CM6533X1/CM6533DH is compatible with USBAudio Class 1.0 and USB 2.0 Full-Speed, thus it can plug &t play without any additional software installation on major operating systems. The internal DAC and ADC support from 8 - 96 KHz sampling rate and 16/24 bits resolution. The hardware of CM6533,CM6533N,CM6533X1 and CM6533DH are all the same and they only differ in firmware and software.

　　The CM6533/CM6533N/CM6533X1/CM6533DHintegrates equalizer on both playback and recording paths to compensate the frequency response of microphone and headphone.

　　The CM6533/CM6533N/CM6533X1/CM6533DH also integrates 256K Byte flash(Including32KB F/W programming size) and crystal but requires few passive components to make a finish product. Thus, it can save the total BOM cost and PCB area can be smaller.
