Features: I2SoverUSB

      Licensed XMOS USB Audio 2.0 Stereo Driver for Windows can be downloaded from our website

            1)   XMOS 500MIPS chip for transmission of asynchronous USB audio data to I2S line.

                     2)   Sampling frequencies: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz

            3)   Resolution: 16-, 24- and 32-bits.

            4)   I2S, right-justified data, left-justified data (external pin configuration) in 32-bit channel frame. I2S, RJ, LJ and S/PDIF are working simultaneously up to 192kHz.

      5)   DSD Audio over PCM frames. DSD64(2.822400MHz) and DSD128(5.644800MHz) by method DoP with 0x05/0xFA markers. 

      6)   Supports directly PCM1704, PCM63, PCM61, PCM58, PCM56, AD1862, AD1865, AD1861, AD1860, AD1851 and other compatible DACs (44.1kHz to 384kHz).

            7)   Two low jitter oscillators for audio 45.158MHz and 49.152MHz

            8)   Input for external master clock (must be 45.158MHz and 49.152MHz)

                     9)   LP5900 ultra low noise linear power regulators (6.5 uV RMS).

            10)   No switch mode power supplies in the PCB board.

11)  Solid ground plane

12)  Galvanic isolation (outputs, two oscillators and reclock are after the isolator).

13)  Output for DAC configuration in DSD mode.

14)  Automatic detection of data type (PCM or DSD).

15)  Master clock outputs: 45.1584/49.1520MHz or 22.5792/24.5760MHz (I2S 22.5792/24.5760MHz are reclocked by edge from 45.1584/49.1520MHz)  

16)  Three different ways to power the board, available configurations:

      16.1 Power by USB bus

      16.2 The USB part is powered by USB bus, but the generators and the reclock are fed by a separate external power supply

      16.3 Both the USB part and the generators with the reclock are fed by two different external power supplies.

(The selection of a configuration is done by jumpers.)

Batteries or accumulator batteries can be used as external power supply.

Drivers:

·         No drivers needed for MAC OS version 10.6.4 and above.

·         No driver installation required for Linux with UAC2 compliant kernel.

·         ASIO/KS/WASAPI/Direct Sound drivers are necessary for Windows XP to 8 (32 and 64 bit).

      You can download licensed XMOS USB Audio 2.0 Stereo Driver for Windows from our website.

In DSD mode outputs are DATA Ldsd -> DATAi2s, DATARdsd -> LRCKi2s, BitClockDSD -> BitClockI2S.
