CS4334 IIS/I2S to Stereo Analog Audio Signal Transceiver



Welcome to use WONDOM self-made CS4334 IIS/I2S Decode Board with H/P Output. It converts I2S signal into analog signal. And it can be connected with I2S and adjust any sampling rate between 2kHz and 100kHz. The output interface can be connected to headphone or power amplifier which could be used as audio input.

This is a product that can convert S/PDIF and I2S signal to each other. This product can convert the signal S/PDIF into I2S signal, or convert the signal I2S to S/PDIF signal. Signal conversion model can use the hardware setup, and you can also use the software setting. As for the hardware setup, please refer to the silkscreen on PCB. I2S signals and S/PDIF cannot be used as the input or output at the same time . Please turn off the input power supply when you switch the conversion mode. This WM8804 S/PDIF TOSLINK to IIS Converter has one LED indicator which shows the current operation status.And it can be used with WONDOM AA - AB41131 CS4334 IIS/I2S Decode Board with H/P Output.
