OSCILLATION CIRCUIT
The figure below shows the connection example about general resonator. The oscillation circuit has the built-in
resistance (1 MΩ) . The value of capacity (C
resonator.
The most suitable value is different by individual resonator. Please refer to the resonator manufacturer which
you use for the most suitable value.
Input the clock to XIN pin, and do not connect anything with XOUT pin if you use the external clock (you do not
use the resonator).
Note : Note that a jitter characteristic of an input clock may cause an affect a cycle-cycle jitter
• When using the resonator
• When using an external clock
