PCM1710U/1KG4 datasheet by Texas Instruments

PCM1710U/1KG4 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM1710U?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital inputs. This ensures proper initialization of the device.
• How do I configure the PCM1710U for master mode operation?
  To configure the PCM1710U for master mode operation, set the M/S pin high and ensure that the BCK pin is driven by the PCM1710U. The device will then generate the clock signals for the audio interface.
• What is the maximum allowed capacitance on the analog input pins?
  The maximum allowed capacitance on the analog input pins is 10nF. Exceeding this value may affect the device's performance and stability.
• Can I use the PCM1710U with a separate analog and digital power supply?
  Yes, the PCM1710U can be used with a separate analog and digital power supply. However, it is essential to ensure that the analog power supply is well-filtered and decoupled from the digital power supply to prevent noise coupling.
• How do I handle the device's digital output data format?
  The PCM1710U outputs data in a 24-bit, MSB-first, two's complement format. The device can be configured to output data in either I²S or DSP formats. Ensure that the receiving device is configured to match the output format of the PCM1710U.
