8.3.1 Crystal Power Dissipation vs. RLIM

For Figure 6-10, the following applies:

  • The typical RMS jitter values in the plots show the total output RMS jitter (JOUT) for each output buffer type and the source clock RMS jitter (JSOURCE). From these values, the Additive RMS Jitter can be calculated as: JADD = SQRT(JOUT2 – JSOURCE2).
  • 20-MHz crystal characteristics: Abracon ABL series, AT cut, CL = 18 pF, C0 = 4.4 pF measured (7 pF maximum), ESR = 8.5 Ω measured (40 Ω maximum), and Drive Level = 1 mW maximum (100 µW typical).
  • 40-MHz crystal characteristics: Abracon ABLS2 series, AT cut, CL = 18 pF, C0 = 5 pF measured (7 pF maximum), ESR = 5 Ω measured (40 Ω maximum), and Drive Level = 1 mW maximum (100 µW typical).
