LMX2572LPRHAR 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 grounds separate and connect them at a single point. Use a low-ESR capacitor for the VDD pin and a 10uF capacitor for the VREG pin.
  • The PLL loop filter values depend on the specific application and frequency range. Use the TI PLL Loop Filter Calculator tool or consult the TI application notes for guidance on selecting the optimal values for your design.
  • The maximum frequency deviation allowed for the reference clock input is ±50 ppm. Exceeding this limit may affect the PLL's ability to lock onto the reference clock.
  • Use the TI Jitter Calculator tool to estimate the jitter performance of the LMX2572LPRHAR in your specific application. You can also consult the TI application notes for guidance on minimizing jitter in your design.
  • Power up the device in the following sequence: VDD, VREG, and then the reference clock input. This ensures proper device initialization and minimizes the risk of latch-up or other issues.
