PCM1782DBQ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures that the internal voltage regulators are properly initialized.
  • To minimize noise and EMI, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the clock signal traces short and away from the analog signal traces. Additionally, use decoupling capacitors and ferrite beads to filter out high-frequency noise.
  • The maximum clock frequency that can be used with the PCM1782DBQ is 256 fs (384 kHz), but it is recommended to use a clock frequency of 128 fs (192 kHz) or lower to ensure optimal performance and minimize jitter.
  • To configure the PCM1782DBQ for Master Clock Mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and set the SDIN pin to the desired serial data input.
  • The recommended termination scheme for the PCM1782DBQ's digital outputs is to use a 50-ohm resistor in series with a 50-pF capacitor to ground. This helps to reduce reflections and improve signal integrity.
