PCM3001E datasheet by Texas Instruments

PCM3001E Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM3001E?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
• How do I configure the PCM3001E for master mode operation?
  To configure the PCM3001E for master mode operation, set the M/S pin high, and ensure that the BCLK pin is driven by the PCM3001E. The device will then generate the clock signals for the audio interface.
• What is the maximum allowed capacitance for the analog input coupling capacitors?
  The maximum allowed capacitance for the analog input coupling capacitors is 10uF. Exceeding this value may affect the device's performance and stability.
• How do I optimize the PCB layout for the PCM3001E?
  To optimize the PCB layout for the PCM3001E, keep the analog and digital signal traces separate, use a solid ground plane, and minimize the length of the analog input traces. Also, ensure that the power supply decoupling capacitors are placed close to the device.
• What is the recommended clock frequency for the PCM3001E?
  The recommended clock frequency for the PCM3001E is 256fs, where fs is the sampling frequency. This ensures that the device operates within its specified performance parameters.
