DESCRIPTION

The CM6642 is a low power single chip USB 2.0 High-Speed audio codec built-in MCU for flexible

applications. With integrated PWM LED driver and two (2)-channel ADC/DAC and S/PDIF interface

that makes it suitable for headset, headphone,docking, speakers, and microphone applications.

The internal MCU can also be developed to a lot of different applications, such as Microsoft™ Lync /

Skype/VoIP device, Mobile Phone or Tablet/Slate docking device. The CM6642 is compatible with

USB Audio Class 1.0 and USB 2.0 Full-Speed, thus it can plug & play without any additional software

installation on major operating systems. The internal DAC support from 44.1~192 KHz and ADC

support from44.1~192 KHz sampling rate with 16/24 bits resolution.

The CM6642 also integrates 16K Byte OTP 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.
