PCM1794AQDBRQ1 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital power supplies (VCCIO and VCCPLL). 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 keep the clock and data lines as short as possible. Also, use a low-impedance path for the analog output and decouple the power supplies with capacitors.
  • The maximum clock frequency is 256 fs (384 kHz), but it's recommended to use a clock frequency of 128 fs (192 kHz) or lower to ensure optimal performance and minimize jitter.
  • To configure the PCM1794AQDBRQ1 for Master Clock Mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Also, set the WS pin to the desired word select frequency, and configure the serial data format using the SDIF pin.
  • The recommended operating temperature range is -40°C to 85°C, but the device can operate up to 105°C with reduced performance and reliability.
