Figure 11.9: Crystal Driver Negative Resistance as a Function of Drive Level Setting
Crystal parameters:
Crystal frequency 16MHz (Refer to your software build release note for frequencies supported)
Crystal C₀ = 0.75pF
Circuit parameters:
C_trim = 8pF, maximum value
C_t1,C_t2 = 5pF (3.9pF plus 1.1 pF stray)
(Crystal total load capacitance 8.5pF)
Note:
This is for a specific crystal and load capacitance.
