    Singxer SDA-1 AK4493EQ I2S XMOS USB HiFi DAC 384KHz DSD512 DOP Decoder


    Feature:
     
    -The SDA-1 is a high-performance DAC that has been developed by our Singxer team for more than two years. It uses XMOS latest xCORE-200 series chip as the USB Audio program, the AKM third-generation flagship DAC as the main chip digital-analog conversion, AK4118 as a digital audio input receiver chip, the use of STM32 as the control core machine, Xilinx Large-scale FPGA as a clock system and digital audio stream processing. PCM up to 384Khz, DSD using native direct solution technology, up to DSD512.
    -Has a rich input and output interfaces, including standard USB2.0 input interface, SPDIF and BNC coaxial and AES balanced input, HDMI-I2S input interface, analog output XLR balanced output and RCA single-ended output; full interface supports DSD input.
    1. Independent research and development of adaptive clock system technology, built-in 4 independent ultra-low jitter audio crystal oscillator for the USB part of the configuration of the local clock system femtosecond level (customized version of CCHD-575);
    2. High-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the external digital input jitter secondary PLL;
    3. Source synchronization technology and FPGA shaping technology, after the isolation of the I2S signal reshaping, thus eliminating the added chip caused by the jitter;
    4. The original multi-input channel isolation technology to ensure the purity of each input signal.
     
    Each interface electrical standard:
    1, USB input socket for the standard USB-B-type female, USB power supply range 4.5V-5.1V;
    2, SPDIF interface input standard S / PDIF signal, the input impedance of 75 ohms, AES input impedance of 110 ohms;
    3, the power input is 115V / 230V AC, the internal use of TALEMA imported transformers for power supply;
    4, I2S input is LVDS level in the form of HDMI interface, compatible with SU-1 interface;
     
    SDA-1 input multiple choice,5 digital inputs, so the input interface supports DSD.
     
    System compatibility:
    1, Windows 7, Windows 8, Windows 10; 32/64 bit, need to install special driver,please contact us
    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 drivers (tested on Ubuntu and Daphile systems, based on INTEL X86 platform)
    4, Android OS 4.2 and above, need equipment to support OTG function, Android 5.0 system is supported by default, the following recommendations for 5.0 with a dedicated player.
     
    I2S interface with HDMI socket input:
    1. Level of 3.3V LVDS differential signal;
    2.I2S interface compatible with a number of I2S output signal definition, FPGA built-in PCM / DSD signal automatic identification algorithm;
    3.DSD ON signal can also be self-defining, DSD ON this signal can be arbitrarily input to the PIN13,14,15,16 pin socket;
    4.PIN1-3 and PIN7-9 phase adjustable, the user can configure the phase of these two pairs of outputs through a switch.
     
    Specifications: Each input interface supports the sampling rate.
    -PCM: 44.1KHz, 48KHz, 88.2KHz, 96KHz,176.4KHz, 192KHz, 352.8KHz, 384KHz
    [Among them USB and I2S support all sampling rate, S / PDIF supports up to 192KHz]
     
    -DSD: 2.8 MHz (DSD64) - DoP, native
              5.6 MHz (DSD128) - DoP, native
