DT-26, 32.768kHz OSCILLATION CIRCUIT EVALUATION（KDS）
1. CRYSTAL UNIT SPECIFICATIONS AND CIRCUIT CONDITIONS
<Crystal Unit Specifications>
KDS P/N: 1TD125DHNS004
Load Capacitance: 12.5pF
*R Specified Value: 40kΩ max.
Room Temp. Deviation: /-20ppm
Turnover Temperature: 25&plu*n;5°C
Parabolic Curvature Constant: -0.04ppm/°C2 max
<Circuit Condition>
Negative Resistance: 5 times more than *R specified value
Drive Level: 2μW max.
2. CONCLUSION
With the current circuit constants, the circuit satisfies the circuit conditions, so that there would be no
problem with oscillation.
[Note]
These *ysis results are from only the circuit board we received this time, and we are not
considering the tolerance or deviation of the m* production. So, we recommend confirming more
circuit boards for the m* production board at your side.
