DAC upgrade board I2S frequency-up 192K/24BIT SRC4192 |

I2S frequency-up 192K/24BIT board for improving the decoding effect of DAC

Using the best SRC4192 chip at present, IS2 input is asynchronously raised to 192K sampling rate, 24-bit data output, and the highest sampling rate is 212 kHz.

Dynamic range: 144 dB (- 60 dBFS input,BW = 20Hz to FS/2, A weighting)

THD + N:-140 dB (0 dBFS relative input, BW = 20Hz to FS/2)

Through resistance change, I/O format support: I2S, left alignment, right alignment, TDM mode

Default input format - - - I2S

Default output format - I2S 192khz/24bit

Matters needing attention:

1. This board is only suitable for CMOS level input, not TTL level input. The simple judgment method is to measure the output signal foot voltage with a multimeter when it is not connected to this board. If it is about 1.6 volts, it will be suitable. Otherwise, it will not be able to use about 2.5V. Otherwise, it will burn the chip and burn the chip wrongly.

2. DAC using this product must support 192K/24-bit decoding, otherwise it can not be used. If you do not understand, please refer to the chip manual.

3. There is a certain risk in refitting. Only with the electronic foundation can we start. Our shop is not responsible for any damage during the refitting process.
