DESCRIPTION
The CM6327A is C-Media's new Audio SOC IC designed for advanced VolP applications. It boasts a high-performance mono ADC, as well as I2C interface, that allows for communication with various microprocessors and DSPs. The CM6327A offers low-noise, high-quality speech input, important when it comes to recording or
broadcasting conference calls or public speeches.Also, the CM6327A integrates all essential analog modules, including 1-ch ADC, PLL, regulator and USB transceiver modules, along with an EEPROM that allows you to customize the product string , PID and VID. Sampling rates of 8/11.025/ 16/22.05/32/44.1 and 48 KHz, high-quality 1 6-bit resolutions and user-friendly general purpose inputs and outputs for customized functions are supported. In addition, many features can be programmed using an external EEPROM and MCU,which are easily controlled via the HID software interface.
