PCM1789TPWRQ1 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 analog performance, ensure that the analog power supply (AVCC) is decoupled from the digital power supply (DVCC) using separate power planes and decoupling capacitors. Also, use a low-noise, high-PSRR voltage regulator for AVCC.
  • The PCM1789 supports clock frequencies up to 256 fs (12.288 MHz) for 24-bit, 192 kHz audio.
  • To configure the PCM1789 for Master Clock Mode, set the MCLK pin as an output by setting the MCLKOE bit in the Control Register. Then, set the desired clock frequency using the MCLKDIV register.
  • The VREF pin is an internal voltage reference output that can be used as a reference voltage for external analog-to-digital converters or other analog circuits.
