PCM2900CDB 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.
  • The analog input filter should be designed to reject noise and aliasing. A 2nd-order Butterworth filter with a cutoff frequency of 10 kHz to 20 kHz is recommended. The filter should also provide a gain of 0 dB to 6 dB to optimize the signal-to-noise ratio.
  • The maximum clock frequency for the PCM2900CDB is 50 MHz. However, the recommended clock frequency is 12.288 MHz to 24.576 MHz for optimal performance.
  • The PCM2900CDB outputs 24-bit data in I²S format. The data is transmitted in a serial format, with the most significant bit (MSB) first. The data is also clocked out on the falling edge of the BCK clock signal.
  • The recommended layout and routing for the PCM2900CDB involves separating the analog and digital sections, using a ground plane, and minimizing noise coupling between the analog and digital signals. The analog and digital power supplies should also be decoupled.
