Singxer Q1 – USB Digital Interface Board – XU208 chip




Singxer Q1


Each output interface supports sample rates:

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

176.4KHz, 192KHz, 352.8KHz, 384KHz

[ Wherein I2S out support full sample rate , S / PDIF supports up to 192KHz]

DSD: 2.8MHz (DSD64) – DoP, native

5.6 MHz (DSD128) – DoP, native

MHz 11.2 (DSD256) –  DoP, Native

[ Wherein I2S out support all DSD format , S / PDIF support DSD64 DOP mode ]

Bits wide:

The highest 32 bit over I2S output

The highest 24 bit over S / PDIF

System Compatibility:

1, Windows 7, Windows 8, Windows 10; 32/64 bit, you need to install special drivers
2, Native MacOS 10.6 and later, using the system comes with drivers
3, Native Linux with UAC2 compliant kernel, using the system comes with the driver (in Ubuntu and Daphile systems tested above, based on INTEL X86 platform)
4, Android OS 4.2 and above, the device needs to support OTG function, in general, Android 5.0 system is supported by default, with recommendation 5.0 below special player.

Q-1 digital interface specification

Q-1 digital interface is Singxer developed a low-cost high-performance USB digital interface, the use of second-generation core XMOS latest USB interface xCORE-200’s, XU208 is U8 upgrade.Q-1 is also a support firmware upgrade interface. Dimensions, screw position, I2S pin position is fully compatible with Italy Amanero module . Please note, schematics and firmware (XMOS) are our own development, not the public version.

We are the world’s first manufacturer to successfully develop with XMOSXU208 chips.



Singxer Q1

The entire board with three crystal design, all imported SMD active crystal oscillator.

Singxer Q1

XU208 is a second-generation XMOS chip memory than U8 double computing speed of terror 1000MIPS , higher than the U8 of 500MIPS doubled.

Each interface electrical standards:

1 , USB input socket is a standard USB-B type female, the USB power supply range 4.5V-5.1V , current probably 110ma.

2 , the I2S pin output level is 3.3V.

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 1 independent way of LDO power supply.

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