LMX2572LPRHAT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a star-connection for the power supply to minimize noise.
  • Use the TI PLL Loop Filter Design Tool or a similar tool to optimize the loop filter design. The tool helps to calculate the component values for the loop filter based on the desired bandwidth, phase margin, and other parameters.
  • Power up the device in the following sequence: VDD, AVDD, DVDD, and finally, the clock input. This sequence helps to prevent latch-up and ensures proper device operation.
  • Use a spectrum analyzer to measure the output spectrum and identify the source of the issue. Check the PCB layout, power supply, and clock input for any noise or jitter. Also, verify that the loop filter is properly designed and implemented.
  • Yes, the LMX2572LPRHAT can be used with a different clock input frequency, but the device's internal PLL must be reconfigured accordingly. Use the TI PLL Calculator tool to determine the required PLL settings for the new clock input frequency.
