PCM1791ADB Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to power up the analog supply (VCCA) first, followed by the digital supply (VCCD), and then the clock signal. This ensures proper initialization of the device.
  • To minimize noise and jitter, 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 a low-ESR capacitor for the analog supply decoupling.
  • The maximum clock frequency that can be used with the PCM1791ADB is 256 fs (384 fs for the PCM1791ADBR), but it is recommended to use a clock frequency of 128 fs or lower to ensure optimal performance.
  • To configure the PCM1791ADB for Master Clock Mode, set the MCKO pin to a logic high, and connect the clock signal to the MCKI pin. The device will then generate the clock signal for the digital audio interface.
  • The recommended termination for the digital audio interface is a 100-ohm differential termination for the I2S and SPDIF interfaces, and a 50-ohm single-ended termination for the AES3 interface.
