Singxer SU-1 XMOS USB Audio Bridge

Beschrijving / Description

SU-1digital interface is our team develop a highperformance USB digital audiointerface, using the XMOS latest xCORE-200 series chip. SU1 is theindependent development low jitter clock digital
system interface (CRYSTEKCCHD-575). SU-1 digital interface using standard USB2.0 input interface, while SU-1 has many output interfaces, including XLR Balanced Output AES, coaxial RCAand BNC, using HDMI socket output I2S port, WCLK /MCLK clock output.

1. The SU-1 is the first domestic and the XMOS latest xCORE - 200 series of USBdigital interface.

A new generation of XMOS chip, using the more advancedprocess technology, the performance was doubled the old one U8 chip, theprocessing capacity of up to 1000 MIPS.

2.Used the high-speed whole isolation design, can beisolation between PC and interface of noise interference cleanly. SU-1 adopteda preeminent circuit design, using the high- speed CPLD/FPGA digital audiosignal for separate after restructuring, so as to make the signal afterreforming completely unaffected by isolation chip itself shaking.

3.SU-1 internal main board adopts the technology of theuniform source synchronous clock, CPLD/FPGA internal using special algorithm ofclock signal and digital audio signal phase control strictly, can ensure thatthe digital audio signal after isolation chip will not appear extra distortionbecause of the time delay and phase difference.

4.SU-1 internal was use of an expensive audio level lowjitter clock (Femtosecond clock), two CCHD -575 are from the Crystek.f5.It is well known that the weight of the core of thedigital audio is algorithm. Singxer team are occupied inthe field of digital audio for many years, at the same time we
get strongsupport from the XMOS FAE team, we are on the basis of the original firmwarehad done many of the technical improvement and optimization algorithm.

Specificaties / Specifications

Each output interface support the sampling rate of:

PCM: 44.1 KHz, 48 KHz, 88.2 KHz, 96 KHz,

176.4 KHz, 192 KHz, 352.8 KHz, 384KHz

[theI2S out and WCLK out support all sampling rate, S/PDIF and

AES/EBU highest support 192 KHZ]

DSD: 2.8 MHz (DSD64) - DoP,native

5.6 MHz (DSD128) - DoP, native

11.2 MHz (DSD256) - DoP, native

[theI2S out support all DSD format, S/PDIF and AES/EBU support DSD64 DOP mode]

bit wide:top to 32 bit over I2S output

top to 24 bit over S/PDIF and AES/EBU output

1. it is a standard USB input socket USB - type Bmother, USB power supply range is 4.5 V to 5.2 V;

2.the AC POWER input socket adopts three oneness of IEC320, support for AC 110 v (90 v to 120 v or 220 v, 180 v to 240v) input, 50 to60 hz, chassis internal ACvoltage switching development.

3.BNC output interface and RCA interface standard,S/PDIF signal level is 550 mv (standard load), theoutput impedance of 75 ohms.

4.XLR output interface standard AES/EBU signal, level of3.3 V (standard load), the output impedance of 110 ohms.

5.the word clock (WCLK) use BNC output interface, forTTL level (no load), the output impedance of 75 ohms.

6.I2S output signal through the HDMI socket, four roadsignal output, including MCLK, BCLK, LRCLK, SDATA signal, using standard anLVDS difference level, impedance control in 100 ohms. One of the HDMI socketPIN13-15 DSD_ON signals, high electricity at ordinary times is I2S work in DSDmode, for

LVTTL level; Weak PIN18 for 5 v power supply output (output currentis less than 20 ma), can be used as an interface plug.
