Application notes
(1) In order to realize low-power operation, the device has a high impedance; the shaded portion in the figure below is highly susceptible to
inductance effects, and should be kept clear of signal lines.
(2) Power supply filter capacitor
To ensure stable operation against transients and noise, connect a bypass capacitor of at least 0.01
μ
F (ceramic) across the power supply,
close to the device.
(3) This device passes a drop test (from 75 cm onto a hard board), but it is possible for the crystal resonator to be damaged by the shocks
produced by some mounting equipment. It is important to confirm that the mounting conditions for the equipment being used do not
adversely affect performance. Re-check if any of the mounting conditions change.
(4) There is a possibility of damage to the crystal resonator during ultrasonic cleaning. Because of the wide variation of conditions in ultrasonic
cleaning equipment, the performance of this device is not guaranteed if it is subject to ultrasonic cleaning.
(5) This is a CMOS device, and the standard precautions against static electricity should be taken.
