PCM2904DB Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This sequence helps prevent latch-up and ensures proper device operation.
  • To optimize the analog input impedance, use a series resistor (Rs) and a capacitor (Cs) in parallel to create a low-pass filter. The values of Rs and Cs depend on the specific application and frequency range of interest.
  • The maximum allowed clock jitter for the PCM2904DB is 100 ps RMS. Exceeding this value may affect the device's performance and accuracy.
  • Yes, the PCM2904DB can be used with separate analog and digital power supplies. However, it's essential to ensure that the analog power supply is clean and free from digital noise to maintain the device's performance.
  • The MCLK and BCLK signals should be treated as high-speed signals and routed carefully to minimize noise and jitter. Use a low-impedance source and a terminated transmission line to ensure signal integrity.
