PCM5142PW Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures proper initialization of the device.
  • To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the analog power supply. Also, ensure that the clock signal traces are short and shielded to minimize jitter.
  • The maximum clock frequency that can be used with the PCM5142PW is 256 fs (frames per second), which corresponds to a clock frequency of 49.152 MHz for a 24-bit, 192 kHz audio signal.
  • To configure the PCM5142PW for Master Clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and configure the device for Master mode using the SPI interface.
  • The recommended termination for the digital output pins of the PCM5142PW is a 50-ohm resistor in series with a 10 pF capacitor to ground. This helps to reduce electromagnetic interference (EMI) and improve signal integrity.
