Feature: 1. Connection: Except for VCC GND, which is connected to power supply, the remaining GND LRCK DATA BCK is connected to I2S signal input. 2. PLL Upfrequency: The internal PLL upfrequency of DAC decoder board is only used to generate internal MCLK clock, which cannot raise the sound sampling rate. 3. I2S Input: DAC decoder module supports direct input of I2S format left justified signal (need to switch manually). 4. Two Filter Modes: This DAC module supports two filter modes, normal mode or low latency mode (set in the board FLT port). 5. With 3.5mm Port: DAC decoder assembled board adds a headphone output interface, which can be directly connected to 3.5mm interface headphones. 6. Premium Sound: Direct output 2.1V RMS sound voltage, high frequency without burr, low frequency full, better dive, beyond ES9023. Specification: Item Type: DAC Decoder Board Material: PCB Power Supply Voltage: DC 5V-10V Maximum Support: 32bit Data 384K Sampling Rate SNR: 112db, Distortion -93db. Package List: 1 x DAC Decoder Board Note: 1. The power supply should not be connected to the reverse, the reverse will damage the board, the voltage exceeds 10V will also damage the board.2. This board does not need to connect to MCLK chip, internal PLL upfrequency generates MCLK clock, which is much better than using asynchronous clock.
