后来到CMEDIA的网站去研究了一番，发现符合用于外置的USB声卡的芯片支持8声道的只有2款，这两款中有一款是支持DOLBY认证的，应该不是，还剩下一款应该就是E95 E96内置USB声卡所采用的音效芯片了，详细资料如下 # p I3 `" R2 e$ g 3 x( t5 x9 R. d5 ^( f# S1 P新推出的CM6308主要是针对USB耳机和声卡：2DAC、2ADC、是建立在CM108的基础上生产出来的，主要功能是支持VISTA系统 7 i2 m7 B1 k6 I 6 T1 x( Y. ?9 z, j! v* FCM6308 USB Audio Solution For Multimedia and Instant Messaging Applications 7 b* I: {* @' x ( ` Q8 f- p2 o& b6 EThe C-Media CM6308 provides an ideal solution for USB headphone, handset, and display phone products, as well as other PC audio and instant messaging applications. It is a highly integrated chip with a wide range of USB audio and telecom voice control capabilities. The CM6308 combines the audio controller and codec, and also integrates I2C and SPI interfaces, for interfacing with external MCU, LCM or DSP chips. Furthermore, the manufacturer string, product string, serial number, product ID, vendor ID, and initial playback and recording volumes can all be customized by interfacing with an external EEPROM.2 C$ W) Q- `' Q
" p9 v+ |( s6 p) a2 }Instant messaging and VoIP software are gaining widespread popularity, as they provide real-time audio/video communication in a cost-effective manner. C-Media not only provides the single chip hardware solution for audio peripherals, but also software middleware that enhances instant messaging programs. - g( V0 @; U* h# H% e; q1 O, K 1 Q' ]8 \) h. lAll essential analog and digital modules are embedded in in the CM6308, including a stereo DAC and stereo ADC, headphone/speaker driving capability, Dynamic Range Compression, Linear microphone gain control, PLL, regulator, USB transceiver, 12 MHz crystal, and power on reset circuit. The CM6308 supports sampling rates of 8KHz, 16Khz, 44.1KHz and 48KHz, with high quailty 16 bit resolution. 2 L y/ e5 I1 r3 Z9 _0 S 8 @6 B) ?1 {+ Z9 N6 VVendors can use the 12 GPIO pins to create a 36 key matrix scan for keypad control functions, saving additional componment cost. Many features are programmable with the external EEPROM and MCU interfaces. Furthemore, MCU/EEPROM/GPIO can easily be controlled through the HID software interface. The buzzer output pin can be easily controlled and changed through software for different frequencies and patterns. In addition, audio adjustments can be made through HID volume control pins. 3 LED indicator pins are supported, to provide more flexible status reporting (On / Off / Operation / playback mute / recording mute) and controllable flash times (using PWM). : R" R, w7 f2 ]* \2 \ & F.
