PCM1704U-J/2K 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 sequence helps prevent latch-up and ensures proper device operation.
  • To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the analog signal sources. Also, use short, direct traces for the analog signals and avoid crossing digital signals over analog signals.
  • The recommended clock frequency for the PCM1704U-J/2K is between 256 fs and 512 fs, where fs is the sampling frequency. This frequency range ensures proper device operation and minimizes jitter.
  • The PCM1704U-J/2K outputs 24-bit data in a 2's complement format. The data should be latched on the rising edge of the clock signal, and the MSB (most significant bit) should be aligned with the clock signal.
  • The recommended operating temperature range for the PCM1704U-J/2K is -40°C to 85°C. Operating the device outside this range may affect its performance and reliability.
