Oscillation Characteristics
31.6
Oscillation characteristics vary depending on conditions such as components used (resonator, R
f
, R
d
, C
G
, C
D
) and
board pattern. Use the following characteristics as reference values. In particular, when a ceramic or crystal resona-
tor is used, evaluate the components adequately under real operating conditions by mounting them on the board
before the external register (R
f
, R
d
) and capacitor (C
G
, C
D
) values are finally decided.
