NEW 1PC I2S up-converted 192K/24BIT board, SRC4192 up-converter board, DAC upgrade board
I2S Upconverted 192K/24BIT Board for DAC Decoding
Adopt the best SRC4192 chip at present, amplify IS2 input asynchronously to 192K sample rate, 24-bit data output, up to 212kHz sampling rate
Dynamic range: 144 dB (-60dBFS input, BW = 20Hz to FS/2, A weight)
THD + N: -140dB (0dBFS relative input, BW = 20Hz to FS/2)
Through the resistance change, input and output formats support: I2S, left-justified, right-aligned, TDM mode
Default input format-----I2S
Default output format ----I2S 192khz/24bit
Precautions:
1. This board is only suitable for CMOS level input. It is not suitable for TTL level input. The simple method is to use the multimeter to measure the voltage of the output signal leg if it is not connected to the board. If it is about 1.6 volts, it is suitable. 2.5V or so can not be used, otherwise it will burn the chip, mistakenly burning chips themselves
2. Use this product&39;s DAC must support 192K/24-bit decoding, otherwise can not be used, do not understand, please see the chip manual
3. There is a certain risk of modification, we must have the electronic foundation of talented hands, what is damaged during the conversion process is not responsible for the shop
