Key Products include:
CM6632A USB 2.0 high-speed audio processor that supports the latest USB Audio Device Class V2.0 and high-definition audio processing applications. The CM6632A provides industry-standard HDA and I2S I/O interfaces, supports a maximum of 10 channels of output and 4 channels of input, and also integrates a 192KHz/24-bit S/PDIF transmitter and receiver, making it very versatile. Furthermore, the CM6632A has an embedded 8051 microprocessor that can enhance the flexibility and functionality with external upgradeable ROM codes. The CM6632A is the most powerful audio core for high-value USB2.0 audio products. CM6632A is also capable of supporting a DSD bit stream output, which is a lossless SACD playback technique in PC/Notebook applications.
CM6500B is a USB 2.0 audio chip builds in 8051 for flexible applications. With internal 2-channel ADC and DAC and S/PDIF interface makes it suitable for Headset, Docking, Speaker and Microphone applications. The internal 8051 can be also developed to a lot of different applications, such as iDevice docking or even Android Phone or Tablet/Slate docking device. CM6500B is compatible with USB audio Class 1.0, so can plug and play without additional software installation on all major operation systems. The internal DAC/ADC and S/PDIF out interface support 48K/44.1KHz sampling rate and 16bit resolution.
CM108AH is a highly integrated single chip USB audio solution. All essential analogue modules are embedded in the CM108AH, including dual DAC and headphone amplifier, ADC, microphone booster, PLL, regulator, and USB transceiver. Many features are programmable with jumper pins or external EEPROM. In addition, audio adjustment can be easily controlled via specific HID compliant volume control pins. For value added application, external codec or audio DSPs can be connected to CM108AH via I2S pin for further processing. 3 GPIO pins can be accessed with customer application software for additional value added application.
