TA= -40 to +85, dd:1.5-3.63 Measured peak-to-peak. Tested with Agilent 53132A frequency counter. Due to the low operating frequency, the gate time must be 100ms to ensure an accurate frequency measurement. Stability is specified for two operating voltage ranges. Stability progressively degrades with supply voltage below 1.5. Measured peak-to-peak. Inclusive of initial tolerance at +25, and variations over operating temperature, rated power supply voltage and load. Core operating current does not include output driver operating current or load current. To derive total operating current (no load), add core operating current + output driver operating current, where output driver operating current = Cdriver*out*Fout. Measured from the time dd reaches 1.5. NanoDriveTM is a SiTime trademark. Absolute Maximum Ratings Attempted operation outside the absolute maximum ratings may cause permanent damage to the part. Actual performance of the IC is only guaranteed within the operational specifications, not at absolute maximum ratings. Parameters Continuous Power Supply oltage Range (dd) Short Duration Max.
