OSCILLATION CIRCUIT
The figure below shows the connection example about general resonator. The oscillation circuit has the built-in
resistance (1 M ) . The value of capacity (C
resonator.
Input the clock to XIN, and do not connect anything with XOUT if you use the external clock (you do not use the
resonator).
DEFINITION OF JITTER
Notes :
Cycle - cycle jitter is defined the difference between a certain cycle and immediately after (or,
immediately before).
When using a resonator
Cycle-cycle jitter
When using an external clock
Output clock
Note that a jitter characteristic of an input clock may cause an affect a cycle-cycle jitter
characteristic.
For more information on the resonator, contact the Fujitsu sales representative.
