PCM1748KEG4 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and the device is properly initialized.
  • To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog signals away from the digital signals. Also, use a low-impedance power supply and decouple the power pins with capacitors.
  • The maximum clock frequency that can be used with the PCM1748KEG4 is 192 kHz. However, the actual clock frequency used may be limited by the specific application and the quality of the clock signal.
  • To configure the PCM1748KEG4 for master mode operation, set the M/S pin high, and connect the BCK pin to the clock source. The device will then generate the clock signal and transmit it to the slave devices.
  • The recommended termination scheme for the PCM1748KEG4's digital outputs is to use a 50-ohm resistor in series with a 50-pF capacitor to ground. This helps to reduce electromagnetic interference (EMI) and improve signal integrity.
