PCM1770PW 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 configure the PCM1770PW for master clock mode, set the MCKI pin to the desired clock frequency, and set the MCKO pin to output the clock signal. Then, set the BCK pin to output the bit clock signal, and set the LRCK pin to output the frame clock signal.
  • The maximum allowed capacitance on the AVCC and DVCC pins is 10uF. Exceeding this value may affect the stability of the internal voltage regulators.
  • The thermal shutdown feature is enabled by default. If the die temperature exceeds 150°C, the device will shut down. To handle this, ensure good thermal design and heat sinking, and consider using a thermal monitoring circuit to detect and respond to thermal shutdown events.
  • Keep analog and digital signals separate, use a solid ground plane, and minimize trace lengths and widths to reduce noise and crosstalk. Also, ensure that the power supply pins are decoupled with capacitors and that the device is placed near the analog and digital power supply pins.
