CM6206
High Integrated USB Audio I/O Controller
DESCRIPTION
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.
