The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital power supply (VCCIO). This ensures that the internal voltage regulators are powered up correctly.
To configure the PCM5100APW for master clock mode, set the MCLK pin to the desired clock frequency, and then set the MCLKDIV pin to select the clock divider ratio. The device will then generate the required clock signals for the DAC and other internal circuits.
To minimize noise and interference, it is recommended to separate the analog and digital signals on the PCB, and to use a ground plane to shield the analog signals. Additionally, use short, direct traces for the analog signals, and avoid routing them near the digital signals or the clock lines.
To optimize the PCM5100APW's performance, use a high-quality power supply with low noise and ripple, and ensure that the analog and digital power supplies are decoupled. Additionally, use a low-noise clock source, and optimize the PCB layout to minimize noise and interference.
The maximum allowed capacitance on the analog output pins is 100 nF. Exceeding this value can affect the stability of the output stage and cause oscillations.
