PCM1870RHFT Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VAA and VDA). This ensures that the internal voltage regulators are powered up correctly.
  • To optimize the PCB layout, keep the analog and digital power supplies separate, use a solid ground plane, and place the analog components (such as capacitors and resistors) close to the device. Also, use a low-impedance path for the clock signal and keep the clock signal away from the analog signals.
  • The maximum clock frequency that can be used with the PCM1870RHFT is 50 MHz. However, the recommended clock frequency is 12.288 MHz or 24.576 MHz for optimal performance.
  • To configure the PCM1870RHFT 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 for the slave devices.
  • The recommended value for the decoupling capacitors for the PCM1870RHFT is 10 uF for VCC and VDD, and 1 uF for VAA and VDA. These capacitors should be placed close to the device and have a low equivalent series resistance (ESR).
