CM6327A

USB Single-Chip Audio Solution for Mono Microphone

DESCRIPTION

FEATURES

The CM6327A is C-Media’s new Audio SOC IC

designed for advanced VoIP 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



USB specification 2.0 full speed-compliant and

USB IF-certified

USB audio device specification 1.0- and USB HID

specification 1.1-compliant

Supports control/interrupt/isochroous data

transfers

USB suspend/resume and remote wake-up

support

broadcasting conference calls or public speeches.

Embedded USB transceiver and power-on reset

circuit

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 16-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.



Single 12MHz crystal input with on-chip PLL

Supports series number string for operation

system detection



Serial EEPROM programming interface supports

customized VID/PID/product and manufacture

strings

EEPROM interface supports 24C02 data format
