PCM1681TPWPQ1 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 PCM1681 supports clock frequencies up to 50 MHz. However, the actual clock frequency may be limited by the specific application and system requirements.
  • To minimize clock jitter and skew, use a high-quality clock source, and ensure that the clock signal is properly terminated and routed. Additionally, use a clock buffer or repeater if necessary, and consider using a clock jitter cleaner or conditioner.
  • The recommended operating temperature range for the PCM1681 is -40°C to 85°C. However, the device can operate up to 125°C with reduced performance and reliability.
