CM6317A is a highly integrated single chip USB audio solution which comprises more USB audio controller and applications. According to coming more experiences in PC USB Audio peripheral from Vendors’ recommend, Cmedia aggressively design one single chip to let vendors to come more integration products, and increase more revenues.
CM6317A contains highly performance ADC, and is extended by additional interface like I2C , SPI , allowing all kinds of Micro processor or DSP to communicate it. Especially in USB Microphone application , CM6317A could give you low noise but high quality speech input solution , thus, when it comes to conference or public speech , it would be wonderful choice for you.
Also, CM6317A integrates all essential analog, 2CH ADC, PLL, regulator, USB transceiver, with external EEPROM to customize your own product string, PID and VID , 8/11/16/22/32/44.1/48KHz sampling rate and high quality 16-bit resolution and friendly general purpose inputs and outputs(GPIO) connect the CM6317A to peripheral hardware, like LED, keypads and buttons, there are many features could be programmable with external EEPROM and MCU. External MCU/EEPROM could be easily controlled via HID software interface. 2 LED indicator pins supported provide more flexible behavior with device on / off / operation / recording mute / and controllable flash time.
