LMK00338RTAR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the clock signal traces short and away from noisy signals. Use a common mode filter or a ferrite bead to reduce EMI.
  • Use a 10uF ceramic capacitor and a 100nF ceramic capacitor in parallel, placed as close as possible to the VCC pin. Add a 1uF ceramic capacitor on the VCCA pin.
  • The LMK00338RTAR supports clock frequencies up to 230.4 MHz, but the maximum frequency may vary depending on the specific application and PCB layout.
  • Use the TI Clock Design Tool or the LMK00338RTAR datasheet to determine the correct register settings for the desired clock output frequency. Consult the datasheet for specific register settings and equations.
  • The typical power consumption of the LMK00338RTAR is 350mW at 3.3V and 230.4MHz. However, power consumption may vary depending on the specific application and operating conditions.
