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 PCM5141PWR for master clock mode, set the MCLK pin as an output by setting the MCLKOE bit in the Clock Control Register (CCR). Then, set the desired clock frequency using the MCLKDIV and MCLKF bits in the CCR.
The maximum allowed jitter on the master clock input is 500 ps peak-to-peak. Exceeding this limit may affect the device's performance and audio quality.
To optimize the PCM5141PWR for low power consumption, use the Power Management Register (PMR) to disable unused blocks and features. Additionally, use the Dynamic Voltage and Frequency Scaling (DVFS) feature to adjust the clock frequency and voltage based on the system's requirements.
The recommended layout and routing for the PCM5141PWR's analog and digital signals is to separate the analog and digital signals as much as possible, and to use differential pairs for the analog signals. Additionally, use a solid ground plane and decouple the power supplies to minimize noise and interference.
