CM119BN - A Highly Integrated USB Audio

Download the CM119BN datasheet PDF. This datasheet also covers the CM119BN-C variant, as both devices belong to the same a highly integrated usb audio family and are provided as variant models within a single manufacturer datasheet.

Description

The CM119BN is a highly integrated, crystal-free USB audio single chip solution optimized for USB headset, headphone, and dongle applications such as VoIP (Voice over Internet Protocol).

Features

  • are programmable with jumper pins or external EEPROM. Vendors can customize unique USB VID/PID/Product String/Manufacture String and min/max/initial volumes to EEPROM. The CM119BN also comes with an anti-pop noise circuits design and internal oscillator which can operate without an external crystal oscillator. BLOCK.

CM119BN USB Audio Single Chip A Highly Integrated USB Audio Single Chip DESCRIPTION The CM119BN is a highly integrated, crystal-free USB audio single chip solution optimized for USB headset, headphone, and dongle applications such as VoIP (Voice over Internet Protocol). All essential analog modules were embedded in the CM119BN including dual DAC and earphone driver, ADC, microphone booster, PLL, regulator, and USB transceiver. It also supports 8GPIO pins. 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. Vendors can customize unique USB VID/PID/Product String/Manufacture String and min/max/initial volumes to EEPROM.
