2. The default output format IIS / 24BIT, can also be changed to 24 left, 16 right-justified format, MCLK frequency 256FS, most suitable DAC, can also be used for existing SPDIF receiving section upgrades, DAC portion can also be used to retrofit CD player   3. You can select active or passive crystal (default is active crystal)   The default is the I2S 16-bit or 24 MCLK and support to the DAC directly connected 256FS   5. DC 5V ~ 12V power supply   6. work in hardware control mode, set aside soft control interface, support SPI and I2C mode,   7. a coaxial and an optical input   8. send a conduct coaxial switch optical converter and output data with one cable   Very suitable for friends like DIY use, high playability   Before making reading:       Interface Description:   CN3 socket following pins required to connect to the machine, the following functions, other outlets do not need to be connected to the machine   1 foot ----- GND ground   2 feet ----- VDD, for the 5V to 12V DC power supply   3 feet ----- BCLK bit clock output   4 feet ----- SDATA data output   5 feet ----- LRCK around the clock output   6 feet ----- MCLK master clock output
