CM6327A
USB Single-Chip Audio Solution for Mono Microphone
DESCRIPTION
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
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 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.
