PCM1702U-KE6 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the digital signals. This ensures proper internal biasing and prevents damage to the device.
  • The analog output filter should be optimized for a cutoff frequency of around 100 kHz to 200 kHz to remove high-frequency noise and ensure a smooth output signal. A simple RC filter or a more complex active filter can be used, depending on the specific application requirements.
  • The maximum allowed input voltage for the analog input pins is VREF + 0.5V, which is typically around 5.5V for a 5V VREF. Exceeding this voltage can cause damage to the device.
  • Clock jitter and skew can be minimized by using a high-quality clock source, such as a crystal oscillator, and ensuring that the clock signal is properly terminated and routed. Additionally, the PCM1702U-KE6 has a built-in clock jitter attenuator that can help reduce the effects of clock jitter.
  • The recommended layout and routing for the PCM1702U-KE6 involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the analog input traces. Additionally, the VREF and VCC pins should be decoupled with high-quality capacitors to reduce noise and ensure stable operation.
