Set B ADAU1643 Development Board (USB+PDM) Compatible with CT7601 USB Interface Support 192K SPDIF with USBi Simulator

Example Routine:

- Type-C connects to a mobile phone or computer to play USB audio, the sampling rate is supported to 32bit/192KHz, and ASIO playback and recording are supported.
- Micro USB connected to mobile phone or computer, default 48KHz sampling, support playback and recording.
- The system main clock is provided by the sam5504 module board, and the SIP3 jumper is connected to the 2/3 end.
- The PDM digital microphone shares the BCLK output of the SAM5504, which is input by the MP7 of the ADAU1463. After gain, the external digital potentiometer VR1 is used for volume control, and the gain EQ is processed as a direct sound.
- The direct sound of the microphone is distributed to: monitor/recording port/sam5504MIC input/ADAU1463 reverb input.
- SAM5504 will do reverberation after inputting the direct sound. The EFFOUT terminal outputs the reverberation effect to the ADAU1463_SDATA_IN2 terminal, and the MUSIC terminal outputs USBaudio to the SDATA_IO3 terminal.
- The ADC/DAC module IIS clock is in master mode and is provided by ADAU1463.
- SAM5504 outputs music signals, reverberation effects, and microphone signal input. The ports connected to ADAU1463 are all set to slave mode, and the clock is provided by SAM5504.
- The global sampling rate of SAM5504 is 48KHz/main mode, including the recording signal provided to him by ADAU1463.
- The sampling rate of ADAU1463 and CT7601 playback and recording interface is changed, which varies with the system setting or the sampling rate of the music itself, 44.1-192k/16bit-32bit. CT7601 is the master mode.
