PCM1739E 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 PCM1739E for master clock mode, set the MCLK pin to the desired clock frequency, and set the MCLKDIV pin to the appropriate division ratio. Also, ensure that the BCK pin is tied to the MCLK pin.
  • The maximum allowed jitter on the MCLK input is 500 ps peak-to-peak. Exceeding this limit may affect the performance of the PCM1739E.
  • To optimize the PCB layout for the PCM1739E, ensure that the analog and digital power supplies are separated, and that the analog signals are routed away from the digital signals. Also, use a solid ground plane and decouple the power supplies with capacitors.
  • The recommended termination for the digital output pins is a 50-ohm resistor in series with a 50-pF capacitor to ground. This helps to reduce electromagnetic interference (EMI) and improve signal integrity.
