PCM1803DB Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures proper initialization of the device.
  • To optimize the analog input stage, use a low-pass filter to remove high-frequency noise, and ensure the input signal is within the recommended common-mode voltage range (VCM). Also, use a high-impedance source and a low-capacitance layout to minimize loading effects.
  • The PCM1803DB supports clock frequencies up to 50 MHz. However, the maximum clock frequency may vary depending on the specific application and system requirements.
  • To minimize the impact of clock jitter, use a high-quality clock source with low jitter, and ensure the clock signal is properly terminated and filtered. Additionally, consider using a clock jitter attenuator or a phase-locked loop (PLL) to further reduce jitter.
  • To minimize noise and ensure optimal performance, use a multi-layer PCB with a solid ground plane, and keep analog and digital signals separate. Route the analog input signals away from digital signals, and use shielding or guard rings to reduce noise coupling.
