PCM2906CDB 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 ensures proper device operation and prevents damage.
  • The analog input filter should be designed to reject noise and aliasing. A 3rd-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 PCM2906CDB is 50 MHz. However, the recommended clock frequency is 44.1 kHz to 48 kHz for audio applications.
  • The PCM2906CDB 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 PCM2906CDB involves separating the analog and digital sections, using a ground plane, and minimizing noise coupling. The analog and digital power supplies should also be separated and decoupled.
