CM6300 contains embedded 2ch output with DRC managements. The Dynamic Range Control function can support high efficiency volume output and implement loudness sound effect, which is similar D class amplifier capability. Moreover, CM6300 supports USB standard HID Interface which provide Volume_up / Volume_dn / Play_mute Butoms and 3 LED indicator pins: On / Off / Operation / playback mute / recording mute / and controllable flash time (with PWM Functions)
Furthermore, the manufacturer string, product string, serial number, product ID, vendor ID, and initial playback and recording volumes can all be customized by an external EEPROM. More flexible and customized design is doable with GPIO pins, which are designed by different USB vendor’s requests.
