PCM1755DBQ 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 prevents any potential latch-up conditions.
  • To minimize noise and EMI, it is recommended to keep the analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the device. Additionally, use a shielded cable for the I2S interface and keep the clock signal traces as short as possible.
  • The maximum clock frequency that can be used with the PCM1755DBQ is 50 MHz. However, it is recommended to use a clock frequency of 12.288 MHz or 24.576 MHz to ensure compatibility with most audio systems.
  • The PCM1755DBQ can be configured for Master or Slave mode by setting the M/S pin high or low, respectively. In Master mode, the device generates the clock signals, while in Slave mode, it receives the clock signals from an external source.
  • The recommended termination scheme for the I2S interface is to use a series resistor (Rs) of 22 ohms to 47 ohms and a parallel capacitor (Cp) of 10 pF to 22 pF at the receiver end. This helps to reduce reflections and improve signal integrity.
