The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures proper initialization of the device.
To configure the TLV320AIC20KIPFBG4 for stereo audio, set the STEREO pin high and use the I2S interface. The device will then output stereo audio data on the DOUT pin.
The maximum clock frequency supported by the TLV320AIC20KIPFBG4 is 50 MHz. However, the recommended clock frequency is 12.288 MHz for optimal performance.
To reduce power consumption, use the power-down mode (PDWN pin) to shut down the device when not in use. Additionally, adjust the clock frequency and analog supply voltage to minimize power consumption.
The recommended layout and routing for the TLV320AIC20KIPFBG4 involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing signal trace lengths to reduce noise and interference.
