PCM1870AYZFT Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VCC, and then the analog power supplies (AVDD and DVDD). This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the PCB layout, keep the analog and digital power supplies separate, use a solid ground plane, and place the analog components (such as capacitors and resistors) close to the PCM1870. Also, use short and direct traces for the audio signals.
  • The maximum input voltage for the PCM1870 is 2.1 Vrms. Exceeding this voltage may cause distortion or damage to the device.
  • To configure the PCM1870 for master clock mode, set the MCLK pin to the desired clock frequency, and set the BCLK pin to the desired bit clock frequency. Also, set the LRCLK pin to the desired left-right clock frequency.
  • The recommended decoupling capacitor value for the PCM1870 is 10 uF to 22 uF, with a voltage rating of 10 V or higher. This helps to filter out noise and ensure stable operation.
