PCM2912PJTR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
  • To minimize noise and EMI, it is recommended to keep the analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the device. Additionally, use a shielded cable for the audio interface and keep the clock signal trace as short as possible.
  • The maximum clock frequency that can be used with the PCM2912PJTR is 50 MHz. However, it is recommended to use a clock frequency of 12.288 MHz or 24.576 MHz for optimal performance.
  • To configure the PCM2912PJTR for master mode operation, set the M/S pin high and the BCK pin as the clock output. Additionally, configure the device for the desired audio format and clock rate using the control registers.
  • The recommended termination scheme for the PCM2912PJTR's digital outputs is to use a 50-ohm resistor in series with a 50-pF capacitor to ground. This helps to reduce reflections and improve signal integrity.
