F-1 digital interface, our team develop a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chips. F-1 use low jitter clock system digital interface. F-1 digital interface using standard USB2.0 input interface.
The new generation XOMS chip of XU208,using more advanced process technology, performance than the older U8 chip doubled, reaching 1000MIPS processing capabilities.
1.F-1 is the first use of XMOS latest xCORE-200 series USB interface digital products. New generation XMOS chip,using more advanced process technology, performance than the older U8 chip doubled, reaching 1000MIPS processing capabilities.
2.It is known that the core of the algorithm is heavy digital audio.Our team in the field of digital audio work for many years, at the same time get XMOS FAE support team, we conducted a number of technical improvements and optimization algorithms on the basis of the original firmware.
Specifications:
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:
2.8 MHz (DSD64) - DoP,native
5.6 MHz (DSD128) - DoP,native
11.2 MHz (DSD256) - native
Each interface electrical standards:
1.USB input socket is a standard USB-B type female, USB power supply range 4.5V-5.1V ;
2.RCA connector outputs standard S/PDIF Electricity level is 550mV(standard connection load),the output impedance of 75 ohms.
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 with a 2-way independent LDO for power supply,part of the clock use ADI's ultra low noise LDO, in order to ensure the ultimate 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 with a special pocessing,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 follow standard design,especially USB high speed signals using a 90 ohm differential impedance control.
System compatible:
1: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
The instruction of I2S output signal scoket:
1.It is High dB mute(DSD ON is DSD data stream)
2.All dB is LVCMOS,Voltage is 3.3V.
3.VD3.3 is output supply,and output electric current 50mA
4.MCLK output 22.5792Mhz or 24.576Mhz clock
5.FS0,FS1,FS2 is sample dB,FS3 not.
6.LRCLK =DSDR,SDATA=DSDL,BCLK=DCLK
