PCM1681PWPR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VA and VB). This ensures proper device operation and prevents latch-up.
  • To optimize the PCB layout, keep analog and digital traces separate, use a solid ground plane, and place decoupling capacitors close to the device. Also, ensure that the analog and digital power supplies are separated and filtered properly.
  • The maximum allowed clock jitter for the PCM1681PWPR is 100 ps RMS. Exceeding this value may affect the device's performance and cause errors.
  • Yes, the PCM1681PWPR can operate in a 3.3V system. However, ensure that the analog power supplies (VA and VB) are also set to 3.3V, and adjust the voltage references accordingly.
  • To troubleshoot issues, start by verifying the power-up sequence, clock signal integrity, and analog power supply voltages. Then, check the device's configuration registers and analog output signals using an oscilloscope or logic analyzer.
