One stop electronic component supply Original CM6646X1 is a USB 2.0 high-speed audio codec with 2-channel DAC and 2-channel ADC

Product Descriptions

The CM6646X1 is a USB 2.0 high-speed audio codec with 2-channel DAC and 2-channel ADC for Gaming Headset applications. It supports two playback audio devices with independent volume control for game and chat. It also supports mixing function for two playback audio devices. Moreover, the CM6646X1 supports I2C, SPI, UART and GPIOs to communicate with external device. There are 5 bands EQ for both playback and recording interface to compensate the frequency response of speaker or MIC unit or to fulfill personal listening experience.

The CM6646X1 is embedded with 8051 MCU and 512KB flash makes it is very flexible to change the USB topology or communicate with external device by changing internal flash code. It also integrates 6 PWM LED drivers for status indication.
