PCM1717E datasheet by Texas Instruments

PCM1717E Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM1717E?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and prevents any potential latch-up conditions.
• How do I configure the PCM1717E for Master Clock mode?
  To configure the PCM1717E for Master Clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and set the SDIN pin to the desired serial data input. Finally, set the MODE pin to '1' to enable Master Clock mode.
• What is the maximum allowed jitter on the Master Clock input?
  The maximum allowed jitter on the Master Clock input is 50 ps RMS. Exceeding this limit may result in errors in the digital-to-analog conversion process.
• Can I use the PCM1717E with a separate analog power supply?
  Yes, the PCM1717E can be used with a separate analog power supply. In this case, the VCC pin should be connected to the digital power supply, and the VDD pin should be connected to the analog power supply. This can help to reduce noise and improve the overall performance of the device.
• How do I implement a mute function using the PCM1717E?
  To implement a mute function using the PCM1717E, simply toggle the MUTE pin high to mute the analog output. When the MUTE pin is high, the analog output will be forced to a high-impedance state, effectively muting the output.
