CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

4.

JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech

Brief TB379.

5. For

JC, the “case temp” location is the center of the exposed metal pad on the package underside.

6. The X1 and X2 pins are connected internally to a crystal and should be a floating electrical connection.

7. The ISL12020M Oscillator Initial Accuracy can change after solder reflow attachment. The amount of change will depend on the reflow temperature

and length of exposure. A general rule is to use only one reflow cycle and keep the temperature and time as short as possible. Changes on the order

of ±1ppm to ±3ppm can be expected with typical reflow profiles.

DC Operating Characteristics - RTC Test Conditions: VDD = +2.7 to +5.5V, TA= -40°C to +85°C, unless otherwise stated. Boldface

limits apply across the operating temperature range, -40°C to +85°C.
