9.4.1 Layout Guidelines

The LMK6L-Q1 can operate up to 1250MHz. To optimize the oscillator's performance, make sure to follow industry-standard high-speed layout guidelines as explained in High-Speed Layout Guidelines. To summarize,

  • Minimize long stubs that create antenna effects and deteriorate output performance.
  • Impedance match the differential output traces to 50Ω single-ended or 100Ω differential to eliminate reflections.
  • Make the output traces as short as possible and of equal length to achieve maximum performance.

Section 9.4.1.1 discusses on providing thermal reliability for good thermal and electrical performance. Section 9.4.1.2 discusses how to maintain signal integrity of the entire system by implementing a good solder reflow profile.
