PCM3060PW datasheet by Texas Instruments

PCM3060PW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM3060PW?
  The recommended power-up sequence is to apply VDD first, followed by VDDA, and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the analog-to-digital converter (ADC) performance for my specific application?
  To optimize ADC performance, ensure proper PCB layout, use a low-noise power supply, and consider using an external reference voltage. Additionally, adjust the ADC clock frequency and sampling rate according to your application's requirements.
• What is the maximum allowed capacitance for the analog input pins?
  The maximum allowed capacitance for the analog input pins is 10 nF. Exceeding this value may affect the ADC's performance and accuracy.
• Can I use the PCM3060PW in a multi-channel audio application?
  Yes, the PCM3060PW can be used in multi-channel audio applications. It has a built-in serial audio interface that supports I2S, DSP, and TDM formats, making it suitable for multi-channel audio processing.
• How do I handle clock jitter and skew in my design?
  To minimize clock jitter and skew, use a high-quality clock source, ensure proper PCB layout, and consider using a clock buffer or jitter attenuator. Additionally, use the PCM3060PW's built-in clock recovery circuitry to reduce jitter and skew.
