Minimum external components are needed for building an USB speaker system, which makes CM102-A/S a simple and very cost-effective solution. Since no driver is necessary for audio playback on all major OS; CM102-A/S provides a truly plug-and-play feature for external digital audio playback. For energy saving, USB suspend mode and resume is supported by CM102-A/S. With power amplifier enable pin and volume control VR input pin, a traditional speaker front panel design can be built. More flexible and customized design is possible with GPIO pin, which is accessible by USB vendor specific request. Features USB 2.0 Full Speed Compatible USB audio device class specification v1.0 Compatible USB bus powered 500mA operation with suspend mode support Single 12MHz crystal input with on-chip PLL and embedded USB transceiver USB audio function topology has 1 input terminal, 1 output terminal, and 1 feature unit Alternate zero bandwidth setting for releasing bandwidth on USB bus during inactive operation Isochronous transfer using adaptive synchronization with internal PLL High performance 48KHz sampling rate for audio playback Embedded high performance 16 bit audio DAC Embedded class AB power amplifier for speaker driving Embedded power on reset block and Power amplifier enable / disable control pin Volume control input with simple external VR circuit GPIO pin for application specific usage S/PDIF output interface Single 5V external power supply with internal power regulation 3.3V IO with 5V tolerance; 3.3V core logics design Compatible with Win 98SE / Win ME / Win 2000 / Win XP, and Mac OS 9 / OS X without additional driver Compact 18 pin SOP package Target application: multimedia USB audio box, decoder integrated, pen driver Dolby Digital Real Time Content Encoder (AC-3) software value added Software Xear 3D Sound Technology With HRTF 3D, EAXTM, Speaker Shifter and Virtual 5.1CH effects Date: 05/21/2003 -2- Version: 1.4 CM102-A/102S Integrated 2 Channel USB Audio Controller PIN DESCRIPTIONS CM102-A/102S PIN # 1 2 3 4 5 6 7 8 9 Signal Name PAEN GPIO XO XI DVDD1 DVDD2 USBDP USBDM DVSS PIN # 10 11 12 13 14 15 16 17 18 Signal Name TEST VREF VOLADJ AVDD LOL LOR AVSS SPDIF Out PDSW Figure 1.
