CM6206
High Integrated USB Audio I/O Controller
1
CM6206 is a highly integrated single chip USB audio solution. All essential analog modules are embedded in
CM6206, including 8CH DAC and earphone buffer, 2CH ADC, microphone gain, PLL, regulator, and USB
transceiver. It is very suitable for high end USB external audio box, USB multi-channel headphone or USB
audio interface multi-channel speaker set application.
Many features are programmable with external EEPROM and MCU interface. In addition, MCU/EEPROM/GPIO
control can easily via HID software interface. Better yet, CM6206 support stereo MIC, phone jack sense,
S/PDIF I/O 48 KHz sampling rate. Moreover, unique patent driver can support world‟s first SPEAKER SHIFTER,
Karaoke and Dolby AC-3 real-time encoder functions.
