SGTL5000XNAA3 datasheet by Freescale Semiconductor

SGTL5000XNAA3 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the SGTL5000?
  The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is stable before the digital circuitry is powered up.
• How do I configure the SGTL5000 for a specific audio application?
  The SGTL5000 can be configured using the I2C interface to set the desired audio parameters such as sample rate, bit depth, and audio format. The device also has a set of default settings that can be used as a starting point for configuration.
• What is the maximum clock frequency supported by the SGTL5000?
  The SGTL5000 supports clock frequencies up to 50 MHz, but the recommended frequency is 12.288 MHz for most audio applications.
• How do I handle clock jitter and skew in the SGTL5000?
  The SGTL5000 has a built-in clock jitter attenuator to minimize the effects of clock jitter. Additionally, the device has a clock skew compensation feature to adjust for clock skew between the master clock and the audio clock.
• What is the power consumption of the SGTL5000 in different operating modes?
  The power consumption of the SGTL5000 varies depending on the operating mode. In idle mode, the power consumption is typically around 10 mA, while in active mode it can range from 20 mA to 50 mA depending on the audio format and sample rate.
