It’s a nice, small USB audio interface. Interestingly, it’s the same as the Thunderbolt version, just with an USB-PCIe interface bolted on. The internal PCIe bus is bridged over USB and terminates in a Windows driver that provides a virtual PCIe interface.
Interfaces:
- USB 3
- analog audio
- MIDI
Some Chips:
- Freescale IMX6S5DVM10AB / IMX6S5DVM / IMX6S5 / IMX6: ARM miKrocontroller
- Broadcom/Avago USB 3380: PCIe-USB 3 converter (Super Speed USB)
- Texas Instruments PCM4202: 24-bit, 216 kHz ADC
- Asahi-Kasei AK4396: 24-bit, 216 kHz DAC
