PCM1704U/2K Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This ensures proper device operation and prevents damage.
  • To optimize the analog input filter design, use a low-pass filter with a cutoff frequency of around 10 kHz to 20 kHz to remove high-frequency noise and aliasing. A simple RC filter or a more complex active filter can be used, depending on the specific application requirements.
  • The recommended clock frequency is 256 fs (where fs is the sampling frequency), and the clock jitter tolerance is ±50 ppm. This ensures proper device operation and minimizes errors.
  • The PCM1704U/2K outputs data in a 24-bit, MSB-first, left-justified format. Ensure that the receiving device is configured to accept this format, and adjust the data alignment accordingly to prevent errors.
  • The PCM1704U/2K has a maximum junction temperature of 150°C. Ensure good thermal conductivity between the device and the PCB, and consider using thermal vias, heat sinks, or other thermal management techniques to maintain a safe operating temperature.
