AK4118 Digital Receiver Board Coaxial Fiber AES to I2S Sampling Rate Display

Description: New AK4118 Digital Receiver Board! The board is a finished board! After testing, ship!!!!This board supports coaxial, fiber optic, AES, and I2S/DSD inputs! Select which signal to use through the button and it will be displayed on the display screen! After the input signal is locked, the current sampling rate can be displayed! The board has a power-off memory function, and the next time it is powered on, it will automatically select the channel used last time!When inputting coaxial, fiber optic, or AES, the output I2S signal is in I2S format! When inputting I2S/DSD, the output format is the same as the input I2S/DSD (for some users whose fiber optic cannot reach 192K, please replace the equipment or use coaxial).Signal range supported by coaxial, fiber optic, and AES: 16-24bit 32-192K sampling rate!I2S interface signal range PCM 768K DSD512!In 4118 receiving mode (coaxial, fiber optic, AES mode), the clock 32k-48K corresponds to 256fs, and 88.2k-192K corresponds to 128fs. When inputting I2S, please refer to the device that provides the I2S signal!The DAT-IN (I2S/DSD) input port can be used to connect to a USB interface or other devices that output I2S signals! Can be used to transmit DSD signals as well as DSDON or DSD sampling rate indicator signals and other signals! This I2S input port is a universal I2S interface. As long as the I2S signals output by other devices are connected to the I2S input port using ribbon cables or DuPont cables, as long as the decoding board can support the provided I2S/DSD signals, it can work normally (otherwise it cannot). When the DSDON signal is connected, it can be used to control the decoding board to switch to DSD/PCM mode (the decoding board needs to support DSDON signals), and there will be a display on the screen (the input high-level is DSD, and the low level is PCM. The decoding board must also support the input DSD signal, and if the decoding board does not support DSD, the input DSD cannot work normally). When not using external DSDON signal input, the D/P port on the board can be used to control the input level of this signal (DSDON) by disconnecting it to high and short circuiting it to low!The DAT-IN port is used to input external I2S/DSD signals, and the input signal is directly mapped to the output port.The DAT-IN interface is defined as follows:1-DSDON 2-GND 3-DATA 4-BCK 5-MCLK 6-LRCK 7-ID1 8-ID2 9-GND 10-MUTEThe DOUT port is an I2S/DSD output port. When using coaxial fiber AES input, it can only output I2S signals. When using DAT-IN input, it can directly map the I2S/DSD signals input by the DAT-IN port!The DOUT interface is defined as follows:1-DSDON 2-GND 3-DATA 4-BCK 5-MCLK 6-LRCK 7-OD1 8-OD2 9-GND 10-MUTEUnused signals can be left unconnected. If only I2S is used, only numbers 2-6 can be connected!The BUT interface is used for external buttons and has the same function as the buttons on the board (note that the buttons are not switches).Users using OLED screens should connect to the corresponding OLED display interface according to the same definition. The SLCD1602 (serial port) screen only needs to be connected to 5V, GND, and SDA, with SDA connected to the SD of the display screen. Electrical parameters:Board power supply AC 7.5V-12V!AK4118 board size: 9.53 x 5.03 cmAttention: Please do not attempt or use any functions or parameters that are not written in the introduction, otherwise you will bear the consequences!Regarding the content not mentioned in the introduction, please refer to customer service for accuracy, and our store has the final right of interpretation! As this module is only a part of the entire circuit, our store cannot guarantee that using this module can make the entire circuit work normally (except when matching our equipment according to instructions). This module has undergone strict testing before shipment to ensure that it is in good condition. Therefore, due to the limited DIY ability of the buyer, misoperation, and other factors that cause module damage or malfunction, our store does not provide returns or exchanges!Declaration: This product is a finished board! Only after testing is it sent outDue to the instability of the electronic component market, some components may be out of stock and replaced with other brands, but we guarantee that it will not affect your usage effect!This product has been tested and shipped as a finished product, and no schematic or other documents will be provided at this time!!!
