PCM1851APJTR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper device operation and prevents damage.
  • 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 analog input traces are short and direct to minimize noise pickup.
  • The maximum allowed input voltage is 2.5Vpp differential, exceeding which may cause distortion or damage to the device.
  • To minimize clock jitter, use a high-quality clock source, and consider using a clock jitter attenuator or a phase-locked loop (PLL) to reduce jitter.
  • The recommended operating temperature range is -40°C to 85°C. Operating outside this range may affect device performance or reliability.
