The recommended power-up sequence is to power up the digital supply (DVDD) first, followed by the analog supply (AVDD). This ensures that the digital circuitry is powered up before the analog circuitry to prevent any unwanted analog signals from being generated.
To configure the TLV320AIC23BIPWG4 for stereo audio, you need to set the STEREO bit in the Audio Interface Control Register (AIC23_REG_PAGE0 + 0x10) to 1. This will enable stereo mode and allow the codec to process left and right audio channels separately.
The maximum clock frequency supported by the TLV320AIC23BIPWG4 is 50 MHz. However, the recommended clock frequency is 12.288 MHz, which is the standard clock frequency for audio codecs.
To reduce power consumption in the TLV320AIC23BIPWG4, you can use the Power Down Mode (PDMD) feature. This feature allows you to power down the codec when it is not in use, reducing power consumption to a minimum. You can also adjust the clock frequency and voltage supplies to reduce power consumption.
The recommended layout and routing for the TLV320AIC23BIPWG4 involves keeping the analog and digital signals separate to prevent noise coupling. The analog signals should be routed close to the codec, while the digital signals should be routed away from the codec. Additionally, the power supplies should be decoupled with capacitors to reduce noise.
