PCM1600Y datasheet by Texas Instruments

PCM1600Y Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM1600Y?
  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.
• How do I handle the master clock frequency for the PCM1600Y?
  The master clock frequency should be between 256fs and 512fs, where fs is the sampling frequency. A clock frequency of 256fs is recommended for most applications.
• What is the optimal value for the external capacitor on the VREF pin?
  The recommended value for the external capacitor on the VREF pin is 10uF. This capacitor helps to filter the internal voltage reference and improve the overall performance of the device.
• How do I configure the PCM1600Y for 24-bit audio?
  To configure the PCM1600Y for 24-bit audio, set the DBF (Data Bit Format) pin to logic high and use the 24-bit data format. Additionally, ensure that the sampling frequency is set to 44.1 kHz or 48 kHz.
• What is the maximum allowed clock jitter for the PCM1600Y?
  The maximum allowed clock jitter for the PCM1600Y is 100 ps. Exceeding this value can result in degraded audio performance and increased distortion.
