CM119A High Integration/Low Cost USB Audio Controller DESCRIPTION CM119A is a highly integrated single chip USB audio controller specifically for VoIP (Voice over internet protocol) application. All essential analog modules are embedded in CM119A, including dual DAC and earphone driver, ADC, microphone booster, PLL, regulator, and USB transceiver. It’s also support 8GPIO pins and buzzer output pin for VoIP application. In addition, audio adjustment can be easily controlled via specific HID compliant volume control pins. Many features are programmable with jumper pins or external EEPROM. Vender can customize unique USB VID / PID / Product_String / Manufacture_String to EEPROM for VoIP software authentication.
