USB2.0 highspeed class1 soundcard reference design


(Evaluation board will become available within 2022.)


•  USB 2.0 High-Speed (480MHz) Audio / MIDI system
•  Leading edge performance technology based on an affordable, low current chipset
•  32-bit audio processing with two input and two output channels
•  Samplerates: 44.1kHz, 48kHz, 88.2kHz or 96kHz
•  Optionally four inputs and four outputs at max. 48kHz
•  USB2.0 bus- or self-powered power supply mode
•  On-chip audio PLL is synced to USB SOFs for synchronous applications
•  No samplerate conversion for true 1:1 audio
•  Assignable stereo (1/4” TRS) line input and two headphone outputs on the eval board
•  Up to four MIDI input and output ports (fast USB2.0 I/O bulk transfer)
•  Can be slaved to any I2S digital audio interface (CODEC or ADC/DAC as master)
•  Based on the low cost 32-bit high performance NXP i.MX RT1010 microcontroller


•  For Windows (XP, 7, 8 and 10; 32-bit and 64-bit), Mac OS X, Android, Linux and iOS systems
•  Optional Apple MFi certification possible


•  Plug&Play on Windows (XP - 11) and Mac OS X (USB class1 audio)
•  Works with any Linux or Android device (USB synchronous design)
•  Firmware updating via USB for programming future updates
•  Direct USB2.0 tripple buffer capture and playback for lowest technically achievable latency
•  Long term design experience with hundreds of thousands of USB Audio units licensed worldwide
