Texas Instruments provides a recommended layout and routing guide in the PCM3793ARHBR Evaluation Module User's Guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
The PCM3793ARHBR supports various audio formats, including I2S, TDM, and PCM. Configuration is done through the device's registers, which can be accessed via the I2C or SPI interface. Refer to the datasheet and the PCM3793ARHBR Register Description document (SLAS964) for detailed information on register settings and format configuration.
The PCM3793ARHBR supports clock frequencies up to 50 MHz for the master clock (MCLK) and 24.576 MHz for the audio clock (ACLK). However, the actual clock frequency used depends on the specific application and audio format requirements.
Clock domain crossing occurs when data is transferred between different clock domains. The PCM3793ARHBR has built-in CDC circuits to handle this. However, it's essential to follow proper CDC design practices, such as using synchronizers or FIFOs, to ensure data integrity and prevent metastability issues.
The power consumption of the PCM3793ARHBR depends on the operating mode, clock frequency, and audio format. According to the datasheet, the typical power consumption is around 150 mW. To optimize power consumption, use the device's power-down modes, reduce the clock frequency when possible, and use the dynamic voltage scaling feature.
