PCM1754DBQR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VCCA and VCCD). This ensures proper device operation and prevents latch-up.
  • To optimize the PCB layout, keep the analog and digital power supplies separate, use a solid ground plane, and place the device close to the analog signal sources. Also, use short and direct traces for the analog signals, and avoid crossing digital and analog signals.
  • The maximum allowed clock jitter for the PCM1754DBQR is 50 ps RMS. Exceeding this value may affect the device's performance and cause errors.
  • Yes, the PCM1754DBQR can be used in a 24-bit audio application. Although it is a 16-bit DAC, it can be configured to operate in 24-bit mode by using the MSB of the 24-bit data as the LSB of the 16-bit data.
  • The digital filter coefficients for the PCM1754DBQR are stored in an external memory device. The coefficients can be calculated using the TI Filter Design Tool or other filter design software. The coefficients should be loaded into the external memory device during device initialization.
