SINGXER – F1 – Digital Interface – SPDIF RCA XU208 (Femtosecond CRYSTEK clocks)

Singxer F-1

F-1 digital interface module, the whole network starting. The first use of the second generation XMOS chip developed high-XU208 USB interface, support firmware upgrade. Self-developed schematics and firmware (including XMOS and CPLD), non-reference design.

The reason why Singxer F-1 is so great is that it primarily uses some of the following TECHNOLOGY:

1. Full isolation technology, 150Mbps full-chip isolation, interference can be completely isolated from the PC;
2. Source synchronous shaping technology and CPLD technology, I2S signal isolation after the re-shaping; thus eliminating the isolation chip to bring added jitter;
3. The independent development of the system clock, using femtosecond CRYSTEK custom clock, ultra-low phase noise, low jitter.

F-1 digital interface of our team to develop a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chips. F-1 is the rare use of ultra- low-jitter femtosecond clock digital system interface. F-1 digital interface using standard USB2.0 input interface, while F-1 has a wealth of output interfaces, including coaxial RCA and I2S interfaces.

FEATURES

F-1 is the first using the XMOS latest xCORE-200 series of high-end USB digital interface products.New generation XMOS chip, using more advanced processing technology. It’s performance compared to the older U8 chip has doubled, reaching 1000MIPS processing capabilities.

It is known, the weight of the core is digital audio algorithms. 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.

TECHNICAL SPECIFICATIONS

Wherein I2S out support all DSD format,S/PDIF and AES/EBU support DSD64 DOP mode

BIT DEPTH

• the highest 32 bit over I2S output
• The highest 24 bit over S/PDIF

Screw position,I2S is compatible with Amanero board.

Use three crystal oscillators,they are all active crystal oscillators,and the audio crystal oscillators is CRYSTEK CCHD.

SYSTEM COMPATIBILITY

• Windows 8, 10 & 11; 32/64 bit, you need to install special drivers
• Native MacOS 10.6 and later, using the system comes with drivers
• Native Linux with UAC2 compliant kernel, using the system comes with drivers
• Android OS 4.2 and above, the need to support OTG function.
