Abstract

Universal Serial Bus (USB) audio Devices was applied extensively in current mobile communication equipment, at the same time the low power consumption and high USB bandwidth must be satisfied, we design audio equipment based on USB2.0 High Speed (HS), adopt the latest USB Link Power Management (LPM) protocol issued by USB organization, use Field Programmable Gate Array (FPGA) as the main controller, USB2.0 HS physical layer interface (PHY) was designed externally, and then the USB audio class 3.0 equipment was realized to play music. System analysis and test results show that the system can transmit based on USB2.0 HS, and the average power consumption is lower than the USB1.1 audio equipment, has solved the demand of the high bandwidth and low power consumption of USB audio device effectively.
