PCM1770PWR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the PCB layout, keep the analog and digital power supplies separate, use a solid ground plane, and place the decoupling capacitors close to the device. Also, use a low-impedance path for the analog and digital power supplies.
  • The maximum allowed clock jitter for the PCM1770PWR is 50 ps RMS. Exceeding this value may affect the device's performance and audio quality.
  • To configure the PCM1770PWR 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 recommended operating temperature range for the PCM1770PWR is -40°C to 85°C. Operating the device outside this range may affect its performance and reliability.
