ACCESS: decoder connects to power supply except for VCC GND, the remaining GND LRCK DATA BCK connects to I2S input SUPPORTED FORMAT: Decoder supports I2S format or left justified direct input (manual switching is required), and supports up to 32bit data with a sampling rate of 384K OPTIONAL MODE: The decoder supports two filter modes, normal mode or low delay mode (set at the board FLT port) STABLE OUTPUT: to noise ratio of decoder board is 112db, distortion for 93db, direct output of 2.1V RMS audio voltage, without burr, low frequency is full, good diving TECHNICAL SPECIFICATIONS: This decoder board does not need to connect to the for MCLK chip internal PLL uptick to generate for MCLK clock, which is much using asynchronous clock. The internal PLL uptick is only used to generate the internal for MCLK clock and does not raise the audio sampling rate Item Type: Decoder Module Use: Suitable for player, player, power amplifier equipment, etc. SNR: 112db Distortion: -93db Colour:Black Material:PCB Package Contents: 1 x Audio decoder module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
