PCM55HP datasheet by Texas Instruments

PCM55HP Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the PCM55HP?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures proper internal biasing and prevents latch-up.
• How do I ensure proper termination of the PCM55HP's analog inputs?
  Use a 1 kΩ to 2 kΩ resistor in series with the analog input signal to prevent overvoltage and ensure proper signal termination.
• What is the maximum clock frequency for the PCM55HP?
  The maximum clock frequency for the PCM55HP is 50 MHz. Exceeding this frequency may result in reduced performance or incorrect operation.
• How do I handle the PCM55HP's digital output signals?
  Use a 10 kΩ to 22 kΩ pull-up resistor on the digital output signals to ensure proper signal levels and prevent signal degradation.
• What is the recommended operating temperature range for the PCM55HP?
  The recommended operating temperature range for the PCM55HP is -40°C to 85°C. Operating outside this range may affect performance or reliability.
