PCM3006T/2K datasheet by Texas Instruments

PCM3006T/2K Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM3006T/2K?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper internal biasing and prevents damage to the device.
• How do I optimize the analog input impedance for the PCM3006T/2K?
  To optimize the analog input impedance, use a series resistor (Rs) and a shunt capacitor (Cs) to match the impedance of the input signal. The recommended values are Rs = 1 kΩ and Cs = 10 nF.
• What is the maximum clock frequency for the PCM3006T/2K?
  The maximum clock frequency for the PCM3006T/2K is 256 fs (fs = 44.1 kHz, 48 kHz, or 96 kHz). Exceeding this frequency may result in incorrect data conversion.
• How do I handle the digital output data format for the PCM3006T/2K?
  The PCM3006T/2K outputs data in a 24-bit, MSB-first, two's complement format. Ensure that your receiving device is configured to accept this format to avoid data corruption.
• What is the recommended layout and routing for the PCM3006T/2K?
  To minimize noise and ensure proper operation, keep analog and digital signals separate, use a solid ground plane, and route analog signals away from digital signals. Also, use a decoupling capacitor (e.g., 10 μF) between VCC and GND.
