    CM6206

    Applications

    Introduction

    CM6206 is a highly integrated single chip USB audio solution. All essential analog modules are embedded in CM6206, including 7.1CH 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 Headset or USB multi channel speaker set.

    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 other advanced functions.
