USB2.0 soundcard 192kHz 10in / 10out reference design

Ploytec JCTU prototype board


•  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 10 input and 10 output channels
•  Optionally up to 19 input and 19 output channels at max. 96kHz
•  Optionally up to 36 input and 36 output channels at max. 48kHz
•  Samplerates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz or 192kHz
•  USB2.0 bus- or self-powered power supply mode
•  Sensationally low jitter using an on-chip audio PLL
•  No samplerate conversion or clock recovery for true 1:1 audio
•  Assignable stereo (1/4” TRS) line input and headphone output on the eval board
•  Up to four MIDI input and output ports (fast USB2.0 I/O bulk transfer)
•  SPDIF® or AES/EBU up to 96kHz, 192kHz if JCTU is master
•  Based on the low cost 32-bit high performance NXP i.MX RT1010 microcontroller


•  For Windows (XP, 7, 8, 10 and 11; 32-bit and 64-bit), Mac OS X and iOS systems
•  Optional Apple MFi certification possible
•  Multi-application mode - simultaneous ASIO and/or WDM playback
•  Extremely low latency Windows ASIO and WDM driver (adjustable in multiple parameters)
•  Fully USB Audio Class 2.0 compliant (isoc asynchronous mode)
•  Software installer and advanced ASIO control panel for Windows

ASIO is a trademark and software of Steinberg Media Technologies GmbH.  


•  Firmware updating via USB for programming future updates
•  Handy audiomixer in firmware (low latency monitoring)
•  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
