LMK61E2-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., 100nF) as close as possible to the VCC pin, and a larger capacitor (e.g., 10uF) further away. Ensure the power supply is clean and regulated, and consider adding a voltage regulator if necessary.
  • The recommended clock input signal is a differential signal with a peak-to-peak amplitude of 1.5V to 2.5V, and a common-mode voltage of 1.5V. The clock signal should be AC-coupled to the device.
  • Use the TI Clock Design Tool or the LMK61E2-SIAT datasheet to determine the correct register settings for the desired frequency output. The device can be configured using the SPI interface or by using the internal PLL.
  • The LMK61E2-SIAT is specified to operate from -40°C to 85°C. However, the device can be operated at temperatures up to 105°C with reduced performance and reliability.
