PCM1792ADBR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the analog and digital circuits are powered up in the correct order.
  • To optimize the PCB layout, keep analog and digital signals separate, use a solid ground plane, and place decoupling capacitors close to the device. Also, ensure that the clock signal traces are short and direct to minimize jitter.
  • The maximum clock frequency supported by the PCM1792ADBR is 256 fs (where fs is the sampling frequency). For example, at a sampling frequency of 44.1 kHz, the maximum clock frequency is 11.2896 MHz.
  • To configure the PCM1792ADBR for master clock mode, set the MCLK pin to the desired clock frequency, and set the M/S pin to logic high. Also, ensure that the BCK pin is connected to the clock signal and the LRCK pin is connected to the frame clock signal.
  • The recommended termination for the PCM1792ADBR's digital outputs is a 50-ohm resistor in series with a 10-pF capacitor to ground. This helps to reduce electromagnetic interference (EMI) and improve signal integrity.
