Notes:
2.1 Drive Level (DL)
0.5 μW Max.
(If Drive Level is too high,that may cause crystal resonator abnormal oscillation or damagaed the main
body of quartz.)
2.2 Loading capacitance (CL) :
9.0pF
(The total circuit load capacitance should be equal to the crystal (CL) values, too large or too small load,
will result in frequency drift.)
