The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
To configure the TLV320AIC23BIPWRG4 for stereo audio, set the STEREO bit in the Audio Interface Control Register (AIC23_REG_0) to 1. This enables stereo mode and allows the device to process left and right audio channels separately.
The TLV320AIC23BIPWRG4 supports clock frequencies up to 50 MHz. However, the recommended clock frequency is 12.288 MHz for optimal performance.
To reduce power consumption, use the Power Management Register (AIC23_REG_4) to disable unused blocks, such as the ADC or DAC, when not in use. Additionally, use the Dynamic Power Management (DPM) feature to dynamically adjust power consumption based on the audio signal activity.
To ensure optimal performance and minimize noise, follow the recommended layout and routing guidelines in the datasheet, including keeping analog and digital signals separate, using a solid ground plane, and minimizing trace lengths.
