PCM2900E/2K 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 damage.
  • The analog input filter should be designed to reject noise and aliasing frequencies. A 3rd-order Butterworth filter with a cutoff frequency of around 10 kHz is recommended. The filter should also be impedance-matched to the analog input pins.
  • The maximum input signal amplitude is 2.5 Vrms, which corresponds to a peak-to-peak amplitude of 7.07 V. Exceeding this amplitude may result in distortion and clipping.
  • To configure the PCM2900E/2K for master clock mode, connect the MCLK pin to an external clock source, and set the M/S pin to logic high. The device will then generate the required clock signals for the ADC and DAC.
  • The recommended layout and routing for the PCM2900E/2K involves separating the analog and digital signal paths, using a solid ground plane, and minimizing noise coupling between the analog and digital sections. Additionally, the device should be placed close to the analog input sources to reduce noise pickup.
