1. "We are trying to configure the TAS5719 audio codec's internal PLL clock using a Jetson AGX Xavier development kit."

2. "How do we configure the NVIDIA APE (Audio Processing Engine) to recognize that the codec uses its own PLL in the device tree?"

3. "How do we configure the TAS5719 codec's internal PLL clock?"

Hello,

You don't configure the internal PLL, the only CLK control for the the I2S clock you input in the device. Error handling related to clocks is dependent on the internal PLL of the TAS5719 so you should not drive it externally. PLL control is handled by the device.

Thanks Luis Fernandes de Pina

1.Could you please provide guidance on how to configure the I2S clock settings for the TAS5719 within the context of the NVIDIA Jetson APE (Audio Processing Engine)?

2.Are there any specific device tree configurations for the audio codec TAS5719?

Hello K,

1. Our datasheet outlines the CLK control registers and the serial data interface register to configure as need. How to configure your DSP to transmit I2S is something to look at your DSP documentation or contact your vendor, we cannot provide guidance on this.

2. Can refer to this https://www.ti.com/tool/TAS571XSW-LINUX

best regards,
Luis
