PCM2903CDBR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This ensures proper device operation and prevents latch-up.
  • 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 allowed clock jitter for the PCM2903CDBR is 100 ps. Exceeding this value may result in decreased performance and increased errors.
  • Yes, the PCM2903CDBR can be used with separate analog and digital power supplies. However, it is essential to ensure that the power supplies are properly decoupled and filtered to prevent noise and interference.
  • The PCM2903CDBR outputs data in a 24-bit, MSB-first, two's complement format. The digital output data can be handled using a microcontroller or a dedicated audio codec interface.
