PCM2702E/2K Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures that the internal voltage regulators are properly initialized.
  • To configure the PCM2702E/2K for master mode operation, set the MCLK pin as the clock source, and connect the BCLK and WCLK pins to the external clock source. Also, set the MS bit in the control register to '1' to enable master mode.
  • The maximum allowed capacitance on the VCC and VDD pins is 10uF. Exceeding this value may cause power-up issues or affect the device's performance.
  • During power-down, the digital output pins (e.g., I2S, SPDIF) should be tri-stated to prevent back-powering the device. This can be achieved by setting the output enable pins (e.g., OEN) to '0' or by using an external buffer with a tri-state output.
  • Keep analog and digital signals separate, and use a star-configuration for the analog signals to minimize noise coupling. Also, use a solid ground plane and avoid routing digital signals under the analog signals.
