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 is power hungry(due to linear regulator) but it should favour many people who do not like to use DC-DC convertor. This PCB uses linear regulator and it do not have onchip/onboard DC-DC switching converter.
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. The Xmos used in this pcb is XU216 2000MIPS and it contains two tile. World's first Real 768k USB to I2S/DSD PCB for audiophile Diyer to enjoy! XMOS 768kHz DXD DSD512(DSD1024) high-quality USB to I2S/DSD PCB diynhk already released their own xmos xcore 200 chipset 16 cores but it's diy board
Like you said the new xmos moving so fast.
