Product introduction:
The SDA-2 decoder is a high-performance HiFi audio decoding amp pre-amplifier developed by our team. It uses XMOS''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s latest xCORE-200 series chip as the USB Audio solution and the AKM third-generation flagship AK4497EQ as the main chip. , AK4118 is used as a digital audio input and receiving chip, STM32 is used as the control of the whole machine, and Xilinx''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s large-scale FPGA is used as a clock system and digital audio stream processing. The amp part adopts 4-way fully balanced design and independent discrete Class A amp drive circuit; the front-end output adopts analog front-end design, which is not a way of digital attenuation that affects the dynamics of the sound; has a wealth of input and output interfaces, including standard USB2 .0 input interface, SPDIF coaxial and AES balanced input, analog XLR balanced output, analog RCA output; all interfaces support DSD input.
PCM supports up to 384Khz, DSD adopts native direct solution technology, up to DSD512, and all interfaces support DSD decoding.
DAC chip:Adopt AKM''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s flagship DAC AK4497EQ; DSD adopts the native direct solution mode, the DSD digital stream does not pass through the internal digital filter and modulator, and works in NOS mode. PCM can also choose to work in NOS mode, which conforms to the design idea of ??HQPlayer.
Technical features:
1: The USB part uses our new generation of isolation technology: SCIT technology (Singxer capacitor isolation technique), SCIT technology is a full isolation technology (ground isolation), high-speed signals use 150Mbps isolation chip, low-speed signals use optocoupler isolation, It can completely isolate the interference from the PC; the USB part can basically reach the level of the SU-1 independent digital interface.
2: Source synchronization technology and FPGA shaping technology reshape the isolated I2S signal, thereby eliminating the additive jitter caused by the isolation chip.
3: The self-developed clock system uses a femtosecond crystal oscillator as a local reference clock.
4: 4-way Class A discrete amp circuit, each route is fully balanced amplifier composed of 8 SMD transistors.
