dzsc/19/0819/19081926.jpgDT-26, 32.768kHz OSCILLATION CIRCUIT EVALUATION(KDS)1. CRYSTAL UNIT SPECIFICATIONS AND CIRCUIT CONDITIONS<Crystal Unit Specifications>KDS P/N: 1TD125DHNS004Load Capacitance: 12.5pFESR Specified Value: 40kΩ max.Room Temp. Deviation: /-20ppmTurnover Temperature: 25±5°CParabolic Curvature Constant: -0.04ppm/°C2 max<Circuit Condition>Negative Resistance: 5 times more than ESR specified valueDrive Level: 2μW max.2. CONCLUSIONWith the current circuit constants, the circuit satisfies the circuit conditions, so that there would be noproblem with oscillation.[Note]These analysis results are from only the circuit board we received this time, and we are notconsidering the tolerance or deviation of the mass production. So, we recommend confirming morecircuit boards for the mass production board at your side.
