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 suppose that Singxer SU-1 will work with LKS MH DA003 via I2S port. In such a case, do I have to modify the HDMI cable to fit with both? or just plug in any HDMI cables.  Thank you for your prompt feedback.

Hello, I am very interested in the SU1.  Can you confirm if the SU1 HDMI / I2S interface works with Audio-GD HDMI / I2S interface (I saw from your earlier response that you believe it's same Dip setting like for PS-Audio, but still needed to verify that by a test) ?

I need the product to be shipped to Thailand which is 240v,  However,  the voltage I am using at home is converted to 110v.    How do I arrange to purchase and receive 110v version when I live in a 240v country?    Please advise.

I got email from Shenzhenaudio.com telling me the voltage of the unit is determined by the country the product is shipped to.    So please tell me how to order 110v version and ship to Thailand as your ordering process does not offer a selection to specify voltage.    This is my 3rd time asking how to do this. Please respond with a solution so I can take action on.
