Product introduction:
SDA-1 is a high-performance DAC developed by our Singxer team. It uses XMOS’ latest xCORE-200 series chip XU208 as the USB Audio solution, uses AKM’s third-generation flagship DAC: AK4493EQ as the main chip for digital-to-analog conversion, AK4118 as the digital audio input receiver chip, and uses STM32 as the control core of the whole machine. , Xilinx''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s large-scale FPGA is used as a clock system and digital audio stream processing. PCM supports up to 384Khz, DSD adopts native direct solution technology, and supports up to DSD512.
The DAC chip uses the AK4493EQ released by AKM in early 2018; DSD uses the native direct solution mode, and the DSD digital stream does not pass through the internal digital filter. It works in NOS mode, which is fully in line with The design idea of ??HQPlayer.

I2S interface uses HDMI socket input:
1: LVDS differential signal with a level of 3.3V;
2: The I2S interface is compatible with many I2S output signal definitions, and the FPGA has a built-in PCM/DSD signal automatic recognition algorithm
3: The DSD ON signal can also be defined by itself. The DSD ON signal can be arbitrarily input to the PIN13, 14, 15, 16 pins of the socket
4: The phases of PIN1-3 and PIN7-9 are adjustable, and the user can configure the phases of these two pairs of outputs through a switch
SDA-1 can be configured by SW switch to adapt to different I2S standards.
But as far as we know, the HDMI-I2S of every manufacturer in the world is different. For most manufacturers, HDMI-I2S is a proprietary protocol of the manufacturer.
So, I’m sorry, SDA-1 cannot adapt to all HDMI-I2S devices, so returns due to I2S interface incompatibility are not accepted.
