It is a PCM5102 DAC decoder module. This board does not need to be connected to the MCLK chip.The internal PLL up-frequency generates MCLK clock, which is much better than using asynchronous clock. The internal PLL upscaling is only used to generate the internal MCLK clock and cannot increase the audio sampling rate.
1.It supports 32Bit data
3.It supports up to 384K data sampling rate
4.It has no glitches at high frequencies and fullness at low frequencies
1.Product Name:PCM5102 DAC Decoder Module
2.Power Supply Voltage:DC 5V~10V
3.Signal to Noise Ratio:112db
1.The power supply should not be reversed. Reverse connection will damage the board, and the voltage will also damage the board if it exceeds 10V.
2.Except for the VCC and GND connected to the power supply, the remaining GND,LRCK,DATA and BCK are connected to the I2S signal input.
3.Support I2S format/left-justified signal direct input (requires manual switching).
