LMK61E2BAA-SIAT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the clock signal traces as short as possible and away from other signals. Additionally, use a common mode filter or a ferrite bead to filter out high-frequency noise.
  • Use a low-ESR capacitor (e.g., 0.1uF) as close as possible to the VCC pin, and a larger capacitor (e.g., 10uF) for bulk decoupling. Ensure the power supply is clean and regulated, and use a voltage regulator if necessary.
  • Use a series termination resistor (e.g., 50Ω) at the clock output, and a parallel termination capacitor (e.g., 10pF) to ground. This helps to reduce reflections and ensure signal integrity.
  • Use the TI Clock Design Tool or consult the datasheet to determine the correct register settings for the desired clock frequency. Ensure the crystal oscillator is properly configured and the clock output is enabled.
  • The LMK61E2BAA-SIAT is rated for operation from -40°C to 85°C. However, the device may still function outside this range, but with reduced performance and reliability.
