PLOYTEC USB AUDIO JUNCTION U

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


Ploytec JCTU prototype board




Hardware:

•  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 at 192kHz
•  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 to 768kHz, optionally DSD support
•  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 on chip, optionally ADAT via additional FPGA
•  Based on the low cost 32-bit high performance NXP i.MX RT1010 microcontroller

Software:

•  For Windows (10 and 11, 32-bit and 64-bit), Mac OS, iOS and Linux systems
•  Multi-application mode - simultaneous ASIO and/or WDM playback
•  Extremely low latency Windows ASIO driver (adjustable in multiple parameters)
•  USB interrupt mode transactions on Windows for better performance
•  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:

•  Firmware updating while audio active via USB for programming future updates
•  Audiomixer in firmware (low latency monitoring)
•  USB tripple buffer capture and playback for lowest technically achievable latency
•  Long term design experience with millions of USB Audio units licensed worldwide
