LMX2820RTCR 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-grounding configuration to minimize noise.
  • Use a high-quality external crystal oscillator (XO) with a frequency tolerance of ±20 ppm or better. Ensure the XO is properly matched to the LMX2820RTCR's internal load capacitance (15 pF).
  • The maximum input voltage is 3.6 V, but it's recommended to operate within the 2.7 V to 3.3 V range for optimal performance and to prevent damage to the device.
  • Use the Power-Down (PD) pin to shut down the device when not in use. You can also adjust the clock frequency and voltage regulator settings to minimize power consumption.
  • Use a 10 μF ceramic capacitor in parallel with a 100 nF ceramic capacitor, both connected between the VCC pin and the GND pin, as close to the device as possible.
