DSD1791DBR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in their application note SLAA523, which includes guidelines for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
  • To minimize high-frequency noise, it is recommended to use a low-pass filter, such as a ferrite bead or a pi-filter, on the power supply lines. Additionally, ensure that the PCB layout is designed to minimize loop areas and keep sensitive analog signals away from the digital signals.
  • The maximum clock frequency for the DSD1791DBR is 50 MHz, as specified in the datasheet. However, it is recommended to use a clock frequency of 40 MHz or lower to ensure reliable operation and minimize jitter.
  • The DSD1791DBR's internal registers can be programmed using the SPI interface. Texas Instruments provides a register programming guide in their datasheet, which includes a detailed description of each register and its associated bits.
  • The POR timing for the DSD1791DBR is typically around 10 ms, during which the device is held in a reset state. After the POR timing, the device is released from reset and begins normal operation.
