■ OSCILLATION CIRCUIT
The following schematic on the left-hand side shows a sample connection of a general resonator. The oscillation
circuit contains a feedback resistor (1 M
) . The values of capacitors (C1 and C2) must be adjusted to the optimum
constant of the resonator used.
The following schematic on the right-hand side shows a sample connection of a 3rd overtone resonator. The
values of capacitors (C1, C2, and C3) and inductor (L1) must be adjusted to the optimum constant of the resonator
used.
The most suitable value is different by individual resonator. Please refer to the resonator manufacturer which
you use for the most suitable value.
To use an external clock signal (without using the resonator) , input the clock signal to the XIN pin with the XOUT
pin connected to nothing .
