Description:
SU-1 digital interface of our team to develop a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chip. SU-1 is the independent development low jitter clock digital system interface(CRYSTEK CCHD-575/957 SERIES). SU-1 digital interface using standard USB2.0 input interface, while SU-1 has many output interfaces,including XLR Balanced Output AES,coaxial RCA and BNC,using HDMI socket output I2S port,WCLK clock output.

1.X-1 is the first use of XMOS latest xCORE-200 series USB interface digital products. New generation XMOS chip, using more advanced processing technology, performance is 2 times than the older U8 chip , reaching 1000MIPS processing capabilities.

2.It is known, the core of the algorithm is digital audio. Our team has been in digital audio field for many years, at the same time get XMOS FAE team support, we conducted a number of technical improvements and algorithms optimization on the basis of the original firmware.


Specifications:

Each output interface supports sampling rates:
PCM:
44.1KHz, 48KHz, 88.2KHz, 96KHz,
176.4KHz, 192KHz, 352.8KHz, 384KHz
(I2S support all sampling rate,S/PDIF support upper to 192KHz

DSD:
2.8 MHz (DSD64)-DoP, native
5.6 MHz (DSD128)-DoP, native
11.2 MHz (DSD256)-native
(I2S output support all DSD,S/PDIF,AES/EBU support DSD64 DOP mode)


Bits width:
the highest 32 bit over I2S output
The highest 24 bit over S/PDIF

Each interface electrical standards:
1.USB input socket is a standard USB-B type socket, USB power supply range 4.5V-5.1V;
2.RCA connector outputs standard S/PDIF signal,electrical level is 550mV (standard connection load),the output impedance of 75 ohms.
3.Power suppply input is AC 115V/230V,using TALEMA transformer.

 


Design details:
1.Carry out electricity as the mother of the acoustic design concept,pay attention to the power supply circuit design,high-performance,low noise and fast response of the LDO as the main power source.The entire board using a multi-way independent of the LDO power supply,wherein the clock even partially adopted ADI's ultra low noise LDO,in order to ensure the ultimate output performance.


2.PCB motherboard with 4-layer circuit board design,make sure you have a complete ground plane and power planes, high-speed digital design methods to ensure signal integrity and power integrity of the entire board.The clock signal special treatment, the use of package design and precise impedance control,thereby ensuring the signal quality and increase the clock anti-jamming capability.Input and output signals are to follow standard design,especially USB high speed signals using a 90 ohm differential impedance control.


System compatibility:
1:Windows XP,Windows 7,Windows 8;32/64 bit,need install driver
2:Native MacOS 10.6 and later,use own driver
3:Native Linux with UAC2 compliant kernel,use own driver
4:Android OS 4.2 and above,need support OTG function


I2S port use HDMI socket output:
1.Electrical level is 3.3V LVDS differential signa.
2.DSD ON singnal,5Vpower supply,CPLD has processed the MUTE signal,so do not need to process it again.
3.DSD ON signal can be user-defined,DSD ON signal can be connected to PIN 13,14,15,16 on the socket.
4.You can adjust the phase of PIN 1-3 and PIN 7-9 with a switch.

 

Flexible HDMI-I2S output configuration:
Switch 1-4 is for PIN13-16 on the HDMI socket.
When you turn it into "ON",it means that HDMI PIN has DSD_ON function.
Switch 5 is clock output mode,"OFF" is MCLK,"ON" is WCK.
Switch 6 is for HDMI PIN1-3 and PIN 7-9 phase,ON is positive phase,OFF is negative phase.(ON is for Gustard DAC,OFF is for PS audio)
If it is Gustard DAC,please turn Switch 3 and 6 into "ON",others are "OFF.

Switch 7 and 8 are standby.
The case of formal version(we will write it when formal version finished,now it is not formal version),we will design a hole in the back of the case,so if you want to change configuration,you do not need to open the case.

I connect the SU-1 to my LKS MH DA003 via HDMI/I2S port, the configuration of I2S on the SU-1 is set as follows: Pin 2 and Pin 7 set to 'on'. I use JRiver as software to play music files. Everytime I upsample the music files to DSD , I find that the phase is reverse (left channel become right channel and vice versa), the second problem I encounter is a 'pop' which is very unpleasant everytime I switch to or start a new song. How can I fix these problems? Thank you.

Hi joseph,Pin 2 and Pin 6 set to ON.about the "pop",that is from the LKS,not the SU-1.It is no "POP",if use X20 or PSAUDIO.Thank you.

Hi, I'm experiencing problems in make the SU-1 working with windows 10, I'm using the SU-1 on a PC with windows 10 Pro, JRiver 22 and with the SU-1 I2S output conneced to a PS Audio Directstream DAC, the problem is that the USB drivers aren't working well on win10, if I use the ASIO drivers in JRiver it doesn't work (I get an error message from JR) while using wasapi dirvers it works for few songs and then stop. I tried on two different pc with win10 with the same results, then I tried with another pc with win7 and everything works fine. Seems like the USB drivers are not designed for win10 but for previous version of windows. Do you have other more updated USB drivers for the SU-1? My dedicated PC for audio listening is based on windows10.  Thanks for your support,  Gennaro

Hi Gennaro,  Yes,the manufacturers tell us that they will upgrade drive next year.  If you use WIN10, need to disable digital signature.  You can try.    Thank you.

Hi,  now the SU-1 stopped working at all, I can't see it as a sound device in any PC I connect it to, doesn't matter if win10, win7 or even Mac (I tried with a Macbook pro with Sierra OS where drivers should not be needed). Could be something is wrong with my unit?  Please advice,  thanks  Gennaro
