like you said the new xmos moving so fast . diynhk already released their own xmos xcore 200 chipset 16 cores but it's diy board
XMOS 768kHz DXD DSD512(DSD1024) high-quality USB to I2S/DSD PCB
World's first Real 768k USB to I2S/DSD PCB for audiophile Diyer to enjoy!
dsd 1024 waow
The Xmos used in this pcb is
XU216 2000MIPS and it contains two tile. It is equal to two XU208 combined in one chip, one dedicated tile is used for the USB data and the other tile is dedicated to process the audio data with the DAC.
This PCB uses linear regulator and it do not have onchip/onboard DC-DC switching converter. It is power hungry(due to linear regulator) but it should favour many people who do not like to use DC-DC convertor.
The xmos in this PCB is clocked directly from 45.158Mhz and 49.152Mhz audio oscillator,
the timing and jitter is at less two times better than PCB uses 22.5792MHz 24.576Mhz audio oscillator.
it claim double the f1 1000mips to 2000mips and using ndk crystal clock it cost us89.5
1)
Newest XMOS XCORE-200 2000MIPS 2 Tiles 16 Cores upto 2000MIPS in dual issue mode
2)
4 layer PCB, Solid ground plane (a must for high speed digital circuit)
3)
NDK NZ2520SD Ultra low phase noise oscillator and Murata capacitor sourced from Japan directly (guarantee no fake product from China)
According to the official datasheet,
the phase noise of NZ2520SD is much better than the famous crystek 957 under 25khz(human listenable range)
For easier comparsion(lower is better), we overlay the two phase noise graph at the same scale, under 25khz(human listenable range) nz2520sd(red line) is better, over 25khz(human unlistenable range) crystek 957 is better.
4) Dedicated I2C port for the OLED VU meter display to avoid using the same I2C port control the DAC/ADC chip(if needed) which can causes interference to the DAC/ADC chip (common fault in most design on the market)
5) OLED display is the latest technology with highest contrast, complete dark background, full viewing angle and it looks much better than the commonly used LCD display.
6) Full copper one piece housing, gold plated(not cheaper gold flash) high quality Molex USB connector.
7) Compact size 50mm x 50mm
8)
PCB is powered by external 3.3V(800mA max. 400mA typ.) regulated supply, it is usually connected to the same 3.3v digital power DAC is using(warning: over-voltage or reverse-voltage can damage the xmos chip immediately, double check before power on)
damn to fast now. can you imagine 16core only for usb
also it claims ndk is more better than crystek
i hope u got your damaged dxiopro board replaced with this thing!
if you see cleary seems like diynhk want to beat the singxer face to face . with its spec claim. (double the xmos xcore 208)
now we just wait if diynhk will released a finished product like dxiopro 4a to compete with f1, or maybe even su-1
gonna be interesting!
now melodius, breeze, gustard where is your xmos 200 product . it's hot now!
we can said now 2016 is the year of USB AUDIOPHILE EVOLUTION
