PCM1840IRTWR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization of the device.
  • To optimize the analog input impedance, use a series resistor (Rs) and a capacitor (Cs) in parallel with the input signal. The values of Rs and Cs depend on the specific application and input signal characteristics.
  • The maximum clock frequency supported by the PCM1840 is 50 MHz. However, the actual clock frequency used 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 to maintain signal integrity.
  • To minimize noise and interference, use a multi-layer PCB with a solid ground plane and separate analog and digital power planes. Keep analog and digital signals separate and avoid crossing them over each other. Use short, direct traces for clock and data signals.
