PCM1704U Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This ensures proper device operation and prevents damage.
  • The analog input filter should be designed to reject noise and interference. A simple RC filter with a cutoff frequency of around 10 kHz is recommended. The filter should also be impedance-matched to the analog input impedance of the PCM1704U.
  • The recommended clock frequency is 256 fs (where fs is the sampling frequency). The clock jitter tolerance is ±50 ppm. Exceeding this tolerance may affect the device's performance and accuracy.
  • The PCM1704U outputs data in a 24-bit, MSB-first, two's complement format. The output data is also synchronized with the LRCK (left-right clock) signal. Ensure that the receiving device is configured to accept this data format and synchronization.
  • The PCM1704U has a maximum junction temperature of 150°C. Ensure good thermal conductivity between the device and the PCB, and consider using thermal vias or a heat sink if necessary. Avoid overheating the device to prevent damage or performance degradation.
