PCM5122PW Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
  • To configure the PCM5122PW 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 MCLKFRQ bits in the CCR.
  • The maximum allowed capacitance for the analog output filters is 10nF. Exceeding this value may affect the device's performance and stability.
  • To enter power-down mode, set the PDWN bit in the Power Management Register (PMR). In power-down mode, the device's analog and digital circuits are powered down, but the internal state is retained. To exit power-down mode, reset the PDWN bit.
  • Keep analog and digital signals separate, and use separate power and ground planes for analog and digital circuits. Use short, direct traces for analog signals, and avoid crossing digital signals over analog signals. Follow good PCB design practices to minimize noise and interference.
