Note 1:
Rs < 10
Ω
crystal provides typically a maximum frequency of 40 MHz and Rs<30
Ω
a maximum
frequency of 32 MHz. With Rs = 50
Ω
crystal the maximum frequency is typically 26 MHz.
Note 2:
Crystal Load is at minimum when all CDAC bits are 0s, and at maximum when all CDAC bits are 1s
Note 3:
If the Tri State Output Buffer pin is floating (i.e. PD pin is not connected), the Oscillator is in ON state.
